I played with a Android tablet (sadly can't remember which one!) at CES and wasn't impressed, which bummed me out. I have a droid and liked the idea of staying on one platform.
But i can say i was really impressed with the Blackberry tablet:

Display was great, nice navigation, super fast, USB, has flash and 1080i HD video. Plus they have said it will be cheaper then an IPad last i heard.
