in my personal opinion, all that touch-screen note taking and drawing stuff is really inefficient. The most efficient way to take notes during lecture is import ppts into OneNote and then type notes in the margin. Then when you study, your notes are right there. This means that any computer can get the job done. I wouldn't waste my money on a computer with a bunch of fancy features and upgrades. All you need is something that has a screen with decent resolution and a decent amount of memory and RAM and it shouldn't cost you more than $400 - $500. Take that extra money you would have spent, and put it towards some new shoes/clothes/furniture or whatever.
