I played around with one yesterday, and it seems pretty cool. I haven't really used an ipad though, so I can't compare the two... But the screen seemed really crisp, and everything loaded up really fast.
Try looking at Cnet.com and youtube for some reviews if you're thinking of buying one.
Now I have decided to get this tab but I need to have a feedback from anyone have it already. I did play around with one a bit in a store for some few minutes but that was not enough, I need someone used it for days.
