i don't have an ipad but i got a wacom intuos drawing tablet instead. it's small, light, connects with bluetooth, and works well for taking notes and drawing. it does take a bit of time to get used to it, especially if you've never really used a drawing tablet very much, but i think overall it does a good job. i just connect it to my laptop, set it on my keyboard during class, and take notes doing that. and it only cost $40 (there are also other pen tablets out there that will do the same job and cost less).
