Have the Apple Bluetooth KB and use it with my iPhone. Not in college, but I bought "Awesome Note", and I use it for alot of staff meeting notes. Awesome note allows syncing with Google Docs, which I do after every meeting, so my notes are backed up. Easy to export them to Word or anything from Google Docs. There's probably a note taking app that allows you to draw while note taking, which is the only thing I see harder on the iPhone. I love the setup though.
