I just got my first tablet computer (an Asus Transformer), and of course right away installed KGS to see how it works. I learned what I'm guessing the iPad owners have known for a while now - a tablet really feels like exactly the right kind of computer to play go on. A phone is doable but too small to be perfect, a computer (even a laptop) is a bit big and clunky. With the tablet you just have the board in front of you, at a decent size, and you touch it to drop your stones. It's the next best thing to playing over a real board I think.
The KGS client works pretty well but has lots of room for improvement. Having to press the "chat" button to enter anything is ridiculous, and there's plenty of room for user lists alongside the chat areas. Other things too could be tweaked but those are the top "this is just dumb" things that I noticed.
But sheesh, if I'd known it was this fun I would have shelled out for a Xoom a few months ago. Well, at least I saved some money by waiting.
