I have a Galaxy Note (phone) and find it great as a carry everywhere device for making quick notes. I find it much easier to use the S-Pen to jot things down and the pen also makes it easy to scribble notes/diagrams against PDFs, photos and screenshots. If I was heading back to lectures, I would be looking at the Galaxy Note 10.1 (coming soon) as an alternative to plain pen and paper. Any sort of netbook/laptop is not an option for me - I find a keyboard slows me down and I like the ability to insert arrows and circle/highlight text etc.
