Semi-inspired by the Cell Phone Junkies Thread, I wanted to make a new one solely about mobile OSes. Thanks mostly to the ongoing war for marketshare with the current duopoly of Android and iOS, Windows Phone and BlackBerry competing for third, and the emergence of some very exciting newcomers such as Ubuntu Touch, Tizen, and Firefox OS; I wondered which preference do Hypesters hold to a certain one and why. Is it stability and intuitiveness? Is it brand recognition and reliability of said brand? Or is it perhaps you just plain like it? The poll above features the current Big Four: Android, iOS, BlackBerry and Windows Phone, with Other possibly being either Symbian, MeeGo, or WebOS.
