I might be a little late but i'd like to add my opinion as well. I have used 3 tabs till now. iPad 1, Motorolla zoom and samsung galaxy tab. For me, at the end of the day, the main feature of a tablet is its touch responsiveness. That is the entire backbone of a tablet pc. If its touch is bad, all the other features will lack that punch and control.

My personal opinion is that ipad's touch and responsiveness is far better than any of its competitors. When you use an ipad and compare it to a galaxy tab, you actually feel the ipad's superiority.Sure the galaxy tab has better features, but you cant do jack with those features if basic function of the tab is crippled.

For me ( if you can afford it) Ipad2 is a clear winner, no other tablet can match the responsiveness if its screen.
