Not according to this graph, Apple is #1, Blackberry is #2, and HTC is, indeed, on the 3rd tier. Unless you prefer binary, in which case HTC is 0011b.
# 2. HTC sell more Android phones than Windows phones, so why on earth would they say 30% of their smart phone sales are Windows phones if that is not the case?
The same reason that Blackberry said that the Playbook was an iPad killer, like the HP Slate, the Folio, Dell's version, and finally Microsoft Courier were all built, hyped and then ultimately cancelled. You hype a product in the hopes that some number of the public will buy your product. MSFT did the same thing with Verizon with the Kin 1 and Kin 2 phones. You talk about how many you built (not how few sold), you express optimism and how bright the future is going to be. Then, when your hype ends with a financial analysis; you tuck your tail between your legs and walk away (Kin 1, Kin 2, Zune, Zune HD, etc) and people who bought your sack of goods are stuck with unsupported hardware.
Windows Mobile Mango has failed to meet any of it's sales goals; in fact it's sales goals (which took into account Android and iOS growth) have been missed by 50%. That is, in layman's terms, bad news. MSFT failed to release Win Mobile on time, it was delivered a year later than promised to developers, and if that wasn't bad enough, another 6 months passed before they released the software development kit (SDK) for people to write software for their phone.
When they did release it; they did it with an embarassing parade of hearses with mock-ups of the iPhone, Android and Blackberry in coffins. That is simply humiliating; as an engineer I would have called in sick to avoid the global embarassment of being a part of that spectacle. The days of the world holding their breath for MSFT are over. MSFT has not only failed to inovate, they have failed to copy well.
In a year or two, they will be where Apple will be on the 12th, and where Android will be in 6 months. In the meanwhile, enjoy your MSFT phone, enjoy the 100's of apps in your store. Enjoy it now, and hopefully you'll have even more in a year or so - or you will be the proud owner of a 'collectable' Windows phone when MSFT decides it's lost enough and walks away.
