This comment could have been written a decade ago and it was as laughable back then as it is today. Developers do not dictate the success of a platform. Users do. And they don’t want Linux on the desktop.
Why do users choose a platform? Apps. Who makes the apps? Developers embraced Windows over Mac, users followed. (Until iOS development made Mac's the default dev machine.) Developers embraced iOS and Android over Symbian and webOS. Windows and Mac were great development platforms ten years ago, and iOS and Android were way better than the now-dead competition.
In my family, some of the users chose their platform after asking me what to buy. I'll normally recommend Apple because the hardware is generally pretty good and their service and support through their stores is decent.
Applications usually don't matter, with gaming being the big exception.
If applications really were the biggest factor, Apple probably still wins. Through virtualization, a Mac can legally run more software than any other computer.
> Developers embraced iOS and Android over Symbian and webOS.
Users embraced iOS before developers. The day the iPhone was release, there were far more apps on Windows CE based smartphones but none of that mattered. So I don't think you can say it's all about applications.
