I got to spend about half an hour playing with a hardware reference device not too long ago. While it was fast (and had the best OSK I've used), the UI was just a complete mess. Navigation was clumsy, and it's almost shocking that MS would bring out a platform without multitasking after even Apple has conceded that point. The best description I've heard is that it sort of feels like using iPhone 1.5. That was great in 2007, but I don't know how it's going to fly in 2010/2011 given it's going up against a growing iOS and Android, an entrenched RIM, and potential for HP to breathe new life into the superior WebOS.
