One this has become clear: for about a year now, Android and iOS have commanded the vast majority of the mobile operating system space, at least in smartphones. Together they have made up 85% or more of the mobile space. While their overall gains on the market have slowed, they continue to pile up the installed base and more and more people have chosen them over the “also-rans” of Windows Phone, Blackberry and Bada, and the orphans Symbian, WebOS and Windows Mobile. There are many that are saying “wait, the game is still young” and that other systems will show up to give the top two competition. While obviously you should never say never, I will say that the odds of displacing either iOS, Android or both from the top of the mobile heap are so incredibly long they might as well be zero. As I pointed out in a previous post, the only way to really disrupt them is to change the game. Okay, so why don’t I believe that Blackberry 10, the upgraded Windows Phone, Tizen or the forthcoming Firefox OS will displace the incumbents?
