Hey, remember when Microsoft was primarily a desktop OS company? Well, by the looks of it and despite the attention-grabbing headlines about Xboxes and mobile OS shenanigans, it still is. Either that, or Excel was on the fritz when it added up those 400 million Windows 7 copies and 100 million Office 2010 copies. All of this with a Windows 8 public beta set to make an appearance at CES 2012 and take the ARM world by storm.
Apparently, this milestone also makes it the fastest-selling OS in history, as if it needed a new marketing bullet point. So, those of you looking forward to spending another $100 on the newest Windows incarnation can rest secure in the knowledge that the OS you’re about to throw in the bin was one of the best around when Microsoft made it obsolete just so it can compete in the mobile game.
