Windows

Gartner reported that PC shipments totaled 80.3 million units in Q3. Subtracting an estimated 4.4 million Macs yields an estimated 75.9 million Windows PCs. ((The total will be less than this as some PCs will not ship with Windows))

This total is lower than the total shipped in the same period of 2008.

 

 

The graphs above show the Gartner data and the split between tablets and PCs. ((Tablet and Mac data for Q3 is not yet available))

If we include all iOS and Android devices the "computing" market in Q3 2008 was 92 million units of which Windows ((Windows including Windows Mobile or Windows Phone)) was 90% whereas in Q3 2013 it was 269 million units of which Windows was 32%.

 

Any guesses on what this market will look like in 2018?

Android is the third platform to reach a billion users ((Although activations are not users, I'm assuming that usage is not far behind and the cumulative sales figures I gather are roughly comparable.)) .  The first was Windows and the second was Facebook. Apple sold around 650 to 700 million iOS and is expected to be the fourth to a billion sometime next year. ((Separately, iTunes reports 575 million account holders.))

If we define the Race To a Billion to be bounded by a time limit of 10 years, then Windows does not qualify and Android is actually second. The race is shown in the following graphs (the one on the left is logarithmic scaled, the one to the right includes only a few contenders for illustrative reasons).

Android's activations as reported are shown in the following graph:

Without qualification, Android has been a viral success story. It reached one billion activations in about five years, almost half the time it took FaceBook and far faster than Windows.

However, Android growth can be qualified. I added another set of data which is the number of US Android phone users as deduced from measurements by ComScore. ((ComScore surveys users on their primary phone. Survey includes only those aged over 13 years and excludes phones issued by businesses.))

One way to read the two graphs is: Between March and August, of the 250 million Android devices activated, 4 million were to new Android consumers in the US. In other words, In the last six months, 1.6% of Android activations went toward new usage in the US. The equivalent figure for iOS is about 6%. Note that these are new users, not included are upgrades. It's likely that more of the US buying goes toward upgrades because iOS has been in use longer.

So whereas Android is growing very rapidly, there is a question of reliability of that audience. Engagement is one thing, but in the market which shows highest penetration (and deepest distribution of an alternative) Android is peaking.

 

The most common, almost universally accepted reason for company failure is "the stupid manager theory". It's the corollary to "the smart manager theory" which is used to describe almost all company successes. The only problem with this theory is that it is usually the same managers who run the company while it's successful as when it's not. Therefore for the theory to be valid then the smart manager must have turned stupid at a specific moment in time, and as most companies in an industry fail in unison, then the stupidity bit must have been flipped in more than one individual at the same time in some massive conspiracy to fail simultaneously.

So the failures of Microsoft to move beyond the rapidly evaporating Windows business model are attributed to the personal failings of its CEO. The calls for his head have been getting loud and rancorous for years. Taking this theory further, now that he's leaving, the prosperity of the company depends entirely on the choice of a new (smarter) CEO.

It's all nonsense of course.

Microsoft is composed of people, processes and priorities. And nothing else. The CEO is but one person, admittedly one with a high degree of authority. However, that authority is not unlimited. A change of leadership in a company may have some impact on a larger set of people, at least in the short term, but the bulk of existing resources, institutionalized processes, and priorities set by customers and cash flows limit what any one person can do.

What really causes a company to fail is disruption. The business model around which all products, customers and priorities are built; the culture, the skills and "DNA" of the company; is vulnerable. This vulnerability is why companies have considerably shorter lifespans than the people who work there. They are one of the most fragile of organisms: high infant mortality, with short, unpredictable lives.

Microsoft ascended because it disrupted an incumbent (or two) and is descending because it's being disrupted by an entrant (or two). The Innovator's Dilemma is very clear on the causes of failure: To succeed with a new business model, Microsoft would have had to destroy (by competition) its core business. Doing that would, of course, have gotten Ballmer fired even faster.

Steve Ballmer's only failing was delivering sustaining growth (from $20 to over $70 billion in sales.) He did exactly what all managers are incentivized to do and avoided all the wasteful cannibalization for which they are punished.

If anything, Steve Ballmer avoided The Innovator's Curse. Being successful with new market innovations would probably have led to an even shorter tenure. Destroying prematurely the pipeline of Windows in favor for a profit-free mobile future would have been a fireable offense. Where established large companies are concerned, markets punish disruptors and reward sustainers.

Steve Ballmer will not be remembered as favorably as the man who created Microsoft. But at least he won't be remembered as the fool who killed it. That epitaph is reserved for his successor.

Nokia's Windows (Smart)Phone performance was drowned out last week by Microsoft's big announcement of the Surface inventory write-off. They are pieces of the same puzzle however.

First, a look at Nokia.

There were 7.4 million Lumia phones sold in Q2 with 0.5 million sold in the US. Although Windows Phones grew sequentially from 5.6 million the previous quarter, and up from 4.0 million in the same quarter last year, total smartphones are down y/y and nearly flat over the last four quarters. This is of course because Symbian phones have finally disappeared from volume shipments. The following graph shows the history of Nokia's smartphone shipments.

Although it's tempting to compare Lumia to iPhone (given the premium positioning in the US) the average price of €157 or $206 shows that Lumia is more adequately compared to Android. This is about a third of what Apple gets for its iPhones.

That's not necessarily a bad thing. Nokia's always had a knack for mass-market phones and certainly that was one reason Microsoft was attracted to them. Presumably, the promise of the relationship was to insert Windows Phone into the Nokia development and distribution pipeline, squeezing out costs and filling up channels.

The problem for the brand has been that although priced at Android levels, volumes are nowhere near and the gap is widening. At current activation rates, Android is selling 16.5x faster than Windows Phone (assuming 90% of Windows Phones are Lumia).

So Nokia's problems become Microsoft's problems. As bad as Nokia seems to be doing with Lumia, it's doing a lot better than Microsoft with hardware. Here the story of the great Surface write-off should give pause. Microsoft announced that it would write off $900 million of Surface.  In terms of write-offs this is pretty significant. Compare it with the debacle of the PlayBook write-off when BlackBerry (then known as RIM) wrote off $485 million for tablets it could not sell. Or with Microsoft's own write-off for the Kin which took $240 million out of its shareholder's pockets. The only charge for hardware that I found higher was Microsoft's own Xbox 360 which cost it $1 billion for the "red ring of death".

But this is not an unusual situation at Microsoft. Besides Xbox, Kin and Surface, Microsoft also declared victory in (read: shut down) SPOT watches, the Smart Display, Tablet PCs and the Zune. This is why when I heard about the Surface I asked who would be Microsoft's Tim Cook.

By the way, $900 million write-off could amount to over 3 million devices, more if Microsoft is assuming some residual value in the inventory. Misjudging demand to such a degree that more units are disposed of than sold implies a basic failure of understanding of hardware businesses.

Which brings up the question of what Microsoft will do. They are likely to double down on hardware (also signaled by their re-org) simply because in a device world (read: post-PC) the economics of licensing Windows and Office are evaporating. The price points of EULAs simply don't hold and there are good enough alternatives in use by the hundreds of millions of iOS and Android devices out there already. By withholding Office from iOS and Android, Microsoft has shown a billion people that they can live without it and they already knew they could live without Windows.

So rather than fight, Microsoft chose to switch. Switching from software to hardware, however, is proving very hard. I'm sure quite a bit harder than management  thought.

Last week Frank X. Shaw, VP of corporate communications at Microsoft stated:

 ... most of the people around me were using their iPads exactly as they would a laptop – physical keyboard attached, typing away, connected to a network of some kind, creating a document or tweet or blog or article. In that context, it’s hard to distinguish between a tablet and a notebook or laptop. The form factors are different, but let’s be clear, each is a PC.

Actually this "admission" that iPads are PCs is not something new. Steve Ballmer made the same assertion in 2010 pre-iPad (though calling them slates). Arguably, the notion that tablets are PCs has been dogma at Microsoft for over a decade and Windows running on all form factors has been a strategic guiding principle.

Which is why I've always added the tablet data to the PC data to create a picture of the "personal computing" market. And this is what that picture looks like today:

Note how the share of various platforms has evolved over this brief time span:

Seen this way, Windows has now reached 60% market share and it's likely to dip below 50% during this year. What happens beyond then is harder to imagine. If Windows tablets start growing as fast as the tablet market overall then Windows could stabilize in share. But if Android and iOS tablets follow their phone brethren in growth then it will be far harder for Microsoft to maintain share. But is that cause for concern?

Not necessarily.

The total computing market[1] is likely to expand to over 4 billion users with 1.5 devices per user in the next five years. That expansion implies that 20% share equals more than one billion devices, making such an ecosystem "good enough" for the average developer. It certainly has been good enough for Windows developers to date and they have kept hiring it throughout the new mobile app revolution.

So even if Windows dips to only 20% of the world's computing market it will still be perfectly "viable" for some time to come.

--

1. I define the computing market as the total number of devices which have (a) a CPU (b) a broadband connection (c) a native application execution environment which is open to third party apps. This definition implies the presence of an "ecosystem" which is bound specifically to a platform.

According to Strategy Analytics 3 million Windows-based tablets shipped in Q1. That is not inconsequential. It would add 4% to the total Windows-based computers and reduce the decline in Windows PC growth to -8% (from -11%). You can see the effect of those units on share in the following graphs.

Note the "boundary layer" of pale blue Macs between the brown-hued Windows and the green-hued tablets.

Including tablets of all kinds, here is the market share growth in Windows PCs.

As the post-PC disruption evolves, Microsoft has made an effort to shift its business model. I discussed this some time ago and there remain quite a few questions about the sustainability of the strategy.

However, there might already be evidence that it's working. The clue is in the growth in Windows revenues at a time when PC shipments (at least traditional ones) are declining rapidly. Some of that might be due to deferrals and software assurance revenues which are insensitive to shipments. However some have to be due to the Surface.

Remember that Surface launched with an RT version priced starting at $499 (which did not sell well) but received a boost in Q1 with the Pro version priced at $899 to $999. If we assume a 80:20 mix of Pro to RT and an average price of $950 for the Pro and $550 for RT, 3 million units would generate at least $2.5 billion in gross revenues. Accounting for retail margins of 20%, Microsoft could still be recognizing $2 billion in revenues. That's a significant portion of $5.7 billion in Windows revenue.

We can back into this figure from another direction: Prior to Surface launch, the Windows revenue per PC shipped (combining Microsoft's revenues and Gartner's estimates) was about $50. After the Surface Pro shipped the revenue climbed to $73/PC.

Assuming the same pre-Surface revenue/PC and given the shipment figures for Q1 we would get about $3.7 billion for Windows. The difference to actual revenues is about $2 billion.

So the extrapolation of Windows royalties approach yields $2 billion in Surface sales and the Price x Units estimate also yields $ 2billion. It would suggest that Surface has had a significant impact already: More than a third of Windows revenues depend on it.

[UPDATE: I've been informed that not all the Windows tablet sales reported by Strategy Analytics are Surface products. As many as 1 million might not be. That would reduce the revenues as calculated to about $1.4 billion. In addition, not all Windows revenues are current with much of that deferred. Actual revenues were $4.6 billion. With both of these adjustments considered, the impact of Surface might be only 30%.)

The latest data on PC shipments from Gartner showed a decline of  11.1% from the first quarter of 2012. As we don't yet have the final data on Apple's Mac shipments, I used my estimate of 4.38 million units (14% growth as per NPD estimate for the US) to obtain an estimate of Windows PC shipments.

That number is 74.8 million units. In the first quarter of 2012 the corresponding calculation yields 85.1 million units. That makes Windows PC rate of decline -12%.

The historic shipment data and growth rates are shown below:

 

Note that tablet data is not yet included in the shipments summary. Windows shipments are shown in shades of Brown and tablets in shades of Blue/Green.

The decline in PC shipments is persisting and even accelerating.

Coming only a week after the iPad's launch birthday, it's perhaps a fitting testament to its impact.

On Mar 18, 2013, Rafael Barbosa Barifouse - Redacao Epoca - Editora Globo asked (and I answered):

Q: Why is Samsung creating Tizen?

A: I believe they are collaborating on Tizen development because they want an alternative to Android and because Bada was not good enough to meet that goal. Tizen's roots include contributions from Intel, Nokia and several Japanese companies so it's not Samsung's OS per se. Historically it was the "open" alternative operating system for embedded and mobile systems. See https://github.com/kumadasu/tizen-history/blob/master/tizen-history.pdf for a historic perspective.

In some ways Tizen seems to be a blend of several pieces of code including proprietary Samsung user interfaces. Samsung is presumably interested in having a unique, differentiated experience. This is something every device maker seeks. Put another way, if they did not seek this then it's unlikely that they would be profitable which would also imply that they would not invest in marketing and development of products. As Samsung invests both in marketing and development it can be concluded that they seek to offer a unique value proposition and, in today's market, that means a unique experience.

Does it make sense to create a new mobile OS when it has had so much success with Android?

Samsung would argue that the success it's had is not due to Android but to its products. Arguably they are right because if Android were the valuable component in a phone then buyers would buy the absolute cheapest device that runs Android regardless of brand. That is not the case. People still seek out a particular brand of phone because of the promise it offers. Consumers have been buying more Galaxies than no-name Android phones.

Why is Samsung the most successful company between the Android devices makers?

In my opinion it's due to three reasons:

1. Distribution. Success in the phone business depends in having a relationship with a large number of operators. Samsung had these relationships prior to becoming a smartphone vendor [because it sold all other kinds of phones]. Few alternative Android vendors have the level of distribution Samsung has. For comparison Apple has less than half the distribution level of Samsung and most other vendors have less than Apple.
2. Marketing and promotion. Samsung Electronics spent nearly $12 billion in 2012 on marketing expenses of which $4 billion (est.) was on advertising. Few Android vendors (or any other company) has the resources to match this level of marketing. For comparison, Apple's 2012 advertising spending was one quarter of Samsung's.
3. Supply chain. Samsung can supply the market in large quantities. This is partly due to having their own semiconductor production facilities. Those facilities were in a large part built using Apple contract revenues over the years they supplied iPhone, iPad and iPod components. No Android competitors (except for LG perhaps) had either the capacity to produce components or the signal well in advance to enter the market in volume as Samsung did by being an iPhone supplier.

Tizen was being treated as an OS for low and mid level devices, but recently Samsung said that it will launch a high-end device with Tizen on Q3, an area where it's very successful with Android. What has changed? What does this announcement mean?

Planning for these product launches is done a few years prior to launch. I believe alternatives to the Android line (i.e. Galaxy) have been planned for a long time. Note that Samsung also has a line of Windows Phones and historically has supported Bada, Windows Mobile, Symbian, PalmOS and LiMo smartphone platforms. Samsung's involvement with Android is only about three years old, and arguably only enjoyed two years of prominent growth. That's less than one product launch cycle and far less than a platform or OS development cycle.

I believe the company has a long term perspective and that includes a time span beyond the likely lifetime of Android [Note that platforms do have finite lives]. Keep in mind that phones last less than two years. If users are not loyal to a platform then they will very quickly move on. The "stickyness" of a platform depends on media or software consumption by the user. That level of consumption is not particularly high for most Android users. The same phenomenon happened with Symbian and BlackBerry and Windows Mobile users. Hundreds of millions switched or will switch out of those platforms. This happens far less with iOS, Mac OS X and Windows because of the significant investments users make in the ecosystems above the OS.

Is Google dependent on Samsung's sucess with Android? Or Samsung is more dependent on Android since its the most popular mobile OS nowadays?

Google is not dependent on Samsung because it's not dependent on Android. Samsung is not dependent on Google because Samsung is not dependent on Android. Android is valuable in theory but in practice its value is hard to identify. Historically it was planned as a defense against the hegemony of Windows, BlackBerry and iOS. In that respect it has succeeded. But playing defense is not enough to win a game. For Google to truly succeed in mobile it needs to define a better business model.

So far its profitability from mobile is very weak and has not shown up in the bottom line. Furthermore, it's probable that Google has 'control' over only about 40% of Android devices in use. Control here means a guarantee that users will use those devices for the benefit of Google, and, more importantly, not for the benefit of its competitors.

You can also think of it this way: If they "divorced" there would be minimal to no impact to their fortunes in the foreseeable future. Buyers of Samsung phones will still buy Samsung phones because they will look and feel very similar and Google services will still be available through browsers or apps (e.g. Google maps on iOS). Conversely, users of Google services will continue to use them because they will be available on Samsung devices, no matter what OS is running. The services Google offers are independent of Android and are cross-platform. They will make sure they are available on all major platforms (as they were before and during Android). Google is far more loyal to Search and Maps and Gmail and YouTube than they are to Android.

Do you think Google is going to merge Android with Chrome OS?

Google's chairman said they would so I assume they will.

If so, how this could make an impact on Samsung?

It depends on how the new OS would enforce licensing terms. If the result would be a restriction on Samsung services like S Pen, AdHub, Samsung Wallet, SmartTV, ChatON etc. then Samsung might reject the OS and either fork Android or move to Tizen more broadly.

I last looked at the race to a billion in March 2011. Since then, I've been updating and adding data to the set giving a broader selection of platforms to compare.

Before we dive in, an explanation: the initial review excluded Windows (PC) and Facebook mainly because (a)  the ramp scale I'm using is about a decade in duration and (b) I was reluctant to compare platforms that require payment to join to those that don't. The (DOS/Windows) PC ramped over several decades (starting in 1981) and Facebook is a service that costs nothing to join. There was much gnashing of teeth and shaking of fists as a result.

Therefore, in the interest of inclusion, I added both to the data set and let the chips fall where they may.

The data is shown below.

I kept the scale to about a decade so that individual lines can be resolved. As a result, you'll note that although Windows reached one billion first it did so slowly enough to be off the scale shown. Indeed, the "race to a billion" should be titled  "The race to one billion users in less than a decade".

In such a competition, the winner would be Facebook which, in October 2012, 35 quarters after launch, reached the finish line. The second looks to be Android (probably this year) and the third iOS (sometime next year.)

That may sound like the end of it, but what the graph also shows are the more subtle trends:

• Game consoles seem to saturate at below 100 million total. One can see the difference in ramps between recent mobile platforms and consoles in the second chart. There might be implications for which platforms will end up dominating the entertainment industry. There should also be some explanations of why consoles are so limited.
• iTunes accelerated with iOS and left the iPod behind. This is unsurprising but it shows that a content platform can be more flexible than one attached to any particular device or architecture. An important lesson perhaps for those in the content businesses.
• Early mobile platforms like Nokia's Symbian, RIM BlackBerry and Windows Mobile have faded indicating that there was no early-mover advantage in platforms. The same can be said for early PC platforms.
• Windows Phone began by tracking the Android/iOS ramps but seems not to be accelerating into its second year in a way that implies potential parity.
• Although Facebook did reach 1 billion rather quickly the slopes of Android and iOS indicate that they may overtake it in overall ecosystem size.

One billion is significant in several ways: First, because it is the "high-water mark" set by Windows and signifies what a global platform needs to become to be essentially "universal". Second, because it implies sustainability. A threshold perhaps from which network effects are sufficient to sustain (assuming some switching costs and an ability and willingness to adapt e.g. software, content or time investments from users.) Third, because it implies sufficient value to the ecosystem (assuming a monetization mechanism exists e.g. Windows software developers and IT managers.)

Looking beyond this milestone however, there is no reason why it should be thought of as a barrier. Mobile connections number over 5 billion and computing is likely to reach most of them. Therefore one billion may turn out to be only 20% penetration. In fact, I expect this series of posts will need to be updated in 2013 as "The race to two billion."

Early data shows that the PC market has not experienced a "pop" from Windows 8. Market watchers have been anticipating this pop since every previous version of Windows has led to a surge in shipments. PC vendors have also been hoping for this to lift their volumes. Volumes have been stagnant for a while, as the following chart shows:

If we combine the traditional PC and tablet markets—what I refer to as "large and medium screen PCs"— there has been growth. However the growth is all due to the tablets. When seen in a share split (blue tablets vs. brown Windows PC's) the shift toward tablet computing is clear.

The question is whether Microsoft will be successful in shifting to this new computing model? Microsoft's problem is not that it has difficulty offering an operating system for tablets. The problem is that the economics of both systems and application software on tablets is destructive to its margins.

A PC has for several decades been "taxed"[1] with a Windows and Office license. The exact figure is imprecise because of subscription accounting used by Microsoft, but we can take Microsoft revenues for Windows and Office and divide by PC shipments to get an average.

This view shows how Windows revenues per PC have held steady for the last three years and Office have moved up slightly. In the latest quarter Windows "captured" $52 per PC shipment and Office "captured" $67.

The problem for Microsoft is that pricing systems software at $50 and a suite of apps at $67 for a tablet that costs $200 to the end-user is prohibitive.

Firstly because an OEM could not justify paying $50 to Microsoft while competing with another vendor whose (Android) software license costs nothing. It implies an increase in his bill of materials without the ability to charge more for the product and hence a reduction or elimination of margin.

Secondly because consumers (or IT buyers) would have a hard time justifying $67 for an Office license for every tablet when most apps are either free or under $10. (Apple charges $9.99 each for iOS versions of Pages, Numbers and Keynote which can be installed on several devices.)

The economics of tablets imply a "commoditization" of system and application software. So what's Microsoft to do?

The answer is Surface where the software margin is captured in hardware. This explains the pricing of Surface. The price isn't significantly below what Apple charges because Microsoft wants to capture a comparable (30%+) margin. On a $500 product that amounts to $150. After subtracting hardware operating and distribution costs we can get pretty close to the $120 it currently obtains from a PC.

This also explains the lack of appetite for "partnerships". OEMs which would normally compete on hardware would have to deal with zero margins (or less) after license fees and would be encouraged to cut corners and shave costs, compromising the experience and causing the platform to suffer.

Microsoft does not like the phrase "post-PC" because it implies the end of its hegemony. They like to think of the PC becoming a new form factor in which they have the same role they've always had. However, looking beyond the form factor we see that mobility itself is disruptive in the implied modularity of the PC.

Device economics offer the explanation for an otherwise perplexing Surface strategy. The question remains how many Surface units could Microsoft possibly sell to maintain its revenues.

1. A "tax" is implied only when purchases are mandatory.

This interview was conducted with Bruno Ferrari Editor of Exame magazine in Brazil.

First, do you have forecasts for tablet market share including Microsoft for next years? (Apple, Android, Amazon etc)?

I have some guesses but I don't think it's something that is defensible. Too many things can change. Fundamentally I believe Microsoft sees the tablet as a PC and intends to migrate a substantial portion of would-be PC customers to tablet forms. If they are successful then they preserve the existing PC user base and allow it to grow a bit.

In contrast Apple sees the iPad as a new type of device that is used for things not directly related to PC style computing. In that sense the iPad competes with PC non-consumption. It means people may own both a PC and an iPad and some will own only an iPad. The iPad will expand the market while taking share from the PC. Windows tablets will try to hold the Windows share steady.

 How do you analyze Microsoft’s strategy with Microsoft Surface? Don’t you think they’re admitting themselves that Apple was right since the beginning?

We don't know the strategy yet. Without pricing and an idea of how the other OEMs will respond, I have more questions than answers. The fact that they are doing their own PC hardware does indicate that they see the industry architecture changing and that a large number of vendors offering hardware "choice" is not really the basis of competition in PCs. In other words, buyers are not willing to pay a premium for Windows because the hardware it's available on is offered in a wide range of options.

Do you think MS growth at tablet market will surpass the lost at PC (desktop and notebook) market in the next years?

This is a crucial question. It's possible that Windows 8 on tablets will create new markets, like the iPad has done and it could take the leading role in expanding computing in a post-PC era. However, to do this, Windows 8 and its successors need to be optimized to solve the new jobs people may have for mobile devices. They have to do this even though they need to sustain the old use cases and business models. To succeed Microsoft needs to "fork" the business model and create new ways of profiting from hardware and software. The rumors that Windows 8 RT devices will be sold at a loss is perhaps a hint that this is the plan.

Did you see the rumor of a 199 dollars Surface? If it’s true, do you think is a good strategy?

It all depends on what will be the alternate source of revenue. I assume there will be some sort of subscription service, taking a page from the telecom industry. Perhaps a mixture of Windows Live services (media, documents in the cloud and software updates). We have to see whether subscription computing makes sense for consumers.

How do you see the problem that MS is creating with its OEM by turning itself on a tablet maker?

There is a problem, of course. However here again the question is whether they are moving to an "ecosystem subscription" model and whether they want to offer revenue share to OEMs. If they offer something then Microsoft plays the role of the operator and device makers are paid some up-front subsidy in exchange for keeping their systems locked into the network.

 One more questions: did you already estimate the shipments of Samsung Galaxy Tab since its launch?

Sorry, I don't have the Galaxy Tab estimate. However, here is what I found:

A week after its release, Samsung announced that they had sold 600,000 units. On the 4 December, it was reported that the 1 million mark was reached, two months after launch. However, an executive at Lenovo claimed that Samsung had only sold 20,000 out of the 1 million Galaxy Tabs that were shipped. In January 2011 Samsung announced they had shipped 2 million units to stores. In August 2012, actual sales figures were released in the patent infringement court case against Apple showing that a total of 725,000 Galaxy Tabs were sold through Q2 of 2012.
