If you like your Evo and HTC as the other posters have said wait for the new HTC One Sprint Variant to drop. They've already shown the phone off, and it seems like the perfect phone for you to move to honestly.
HTC One X!
PS: Call me crazy Android GAF, but I don't really own a tablet right now. Not that I wouldn't like one or use the shit out of one if I had it. I just can't justify the price to get one right now especially seeing how fast they are updating. I figure in another year or two Tablets will be really hitting that "good enough" category at laptops hit a few years ago. That being said if Google dropped a 7" Nexus Tablet with ICS for $150 or maybe even $199 I'd be there day one.
