And don't forget the Kin phone Microsoft released a couple years ago (2009/10 IIRC). You know, that was pushed in the commercials where the awkward dude stalked the girl, took pictures of her, and geeked out on his computer about it, while she gives the final "Go To Hell" look at him? Yep, the Microsoft Kin -- the cell phone designed for stalkers.
@Follow Meeee, you are on crack. Microsoft has absolutely failed at mobile devices, including the Zune, Zune HD, Kin, and Surface RT. Considering they have only sold 900,000 Surface RT & Pro tablets with an estimated 6 million unsold devices on hand, nobody can declare their Surface tablets anything like a success. As a retail product, as well as a technology demonstrator to spur other manufacturers to produce Win 8 mobile devices, it is an absolute failure. No other manufacturers are getting behind it.
