I've now been using Windows 10 for a month, and though it's still just an early version with lots of rough edges, I'm convinced that it's going to be a solid desktop operating system for the world's billion-odd mouse-and-keyboard users -- when they finally decide to upgrade from Windows 7 or XP, anyway. It has been slowly dawning on me, however, that Windows 10 is a lost cause; even in a best-case scenario where Microsoft delivers the finest desktop OS to ever grace humankind, there's no getting around the found that Windows 10 is an attempt to revivify a slowly dying beast. While there's always a chance that Windows 10 triggers some kind of renaissance, it's far more likely that it will be squished into ignominious oblivion by the stumbling, apathetic, and commoditized beast that the desktop PC has become.
