Whatever has an AMOLED screen. Its looking like it'll be a Nokia ClearBlack running WP7 or some sort of Samsung Nexus kinda thing. I will certainly miss HTC though when I go!
I know the SLCD's aren't THAT different, but everyone is nitpicky about something and the ever so slight difference just happens to be something that gets to me horribly. I have been intrigued by WP7 for a long time anyways, and I'm sure it will be even more polished by the time I'm ready to peace out the Dinc.
Sense is awesome, and most (non-dev everyday) people I know who have a post-Nexus One HTC phone are in love with it, while there seems to be a large amount of "how come mine doesn't have that" coming from (non-dev everyday) people with other Android devices. I figure the positive feedback I see with WP7 and Nokias recent hardware will give me a solid alternative in 10 months when its time to upgrade.
