Palm Pre user from day one. I think webOS is great, but I think the hardware was lacking. Also add the fact that the SDK and developers still don't have access to hardware pieces like the microphone, bothers me a bit.
I like the size of the Evo (a friend has the HD2 and I think it is great), and while Android may not be as nice as webOS, it is still a good platform and has good momentum. I'll be watching HP and what they do with webOS, but for now, it's Android and Evo's turn with me, and we'll see where thing are next year.
