I got an iPad a few weeks ago. It's a fun gadget, pretty much what you'd expect from Apple. Right now it feels like there aren't that many really useful apps, but I'm sure that within a few months there will be everything you could think of.
One great app that I've been messing around with is the iPad version of Sketchbook Pro. I use the Pogo Sketch stylus with it because drawing with my fingers is just too unwieldly. I find that you have to put something (I use a napkin) under the side of your palm, otherwise the screen registers it as a finger and you get unwanted straight lines. I don't think I'd use an iPad for a final, but for a sketch it's just dandy.
