They kept trying to emulate their desktop success on mobile, build a general purpose operating system and then let any and every hardware manufacturer ship it with their hardware. It worked great on desktop, a thousand IBM clones beat down Apple's proprietary hardware/software combination. They finally realized the same approach might not work on mobile, the experience is more closely tied to the physical hardware then the desktop or even laptop experience will ever be. Killing the current Windows Mobile (6.5) is the best move for MS, as was killing PlaysForSure. If you just try to make everyone happy you end up making no-one happy.
