Unless I am mistaken, Garage Band is Mac, and unlikely to work on most tablets. Mac does have a tablet kicking around, but I haven't actually seen a Modbook. Now PC tablets usually lack RAM and use SD cards to up the storage capacity. So my best guess is that you would be very crippled using a tablet, unless it's a $$$ Mac. Another to consider is the weak video capabilities. All tablets are equipped with embedded graphics processors instead of discrete graphics cards. That may make editing less fun. Even the processor's are slower, but people have been recording to PIII's, so anything can be done. I guess it's up to whether or not you can live with the limitations.
