Windows CE is an unbelievable pile of crap under the hood, easily some of the worst code I've ever seen. It should never have been shipped; it was certainly never made better, at least at a level that mattered. Instead, Microsoft kept adding features. CE speaks volumes about the lack of caring about quality and good design from Microsoft's upper management.

Yes, it was killed a few years ago. But it lasted way too long, and did untold amounts of damage to Microsoft's ability to execute in mobile. They spent a lot of time recovering from many bad decisions, mostly politically driven nonsense having nothing to do with making CE any good.
