I got organised for uni for the first time in my studies, ever.
For first semester, I was doing Chem, Bio, Calculus, and Russian, so I decided that I wouldn't really be using a laptop much at uni because my subjects looked like I'd need to be doing a lot of writing.
I got 4 exercise books that I was sure could fit into binders and an array of display pockets just for loose handouts that are sometimes given in tutorials (i.e. Calculus assignments).
For semester two I treated myself to a netbook and didn't regret a moment of it - I used it religiously for Biology and Russian, however not so much for Physics and Chemistry (these lectures require formula note-taking and diagrams which aren't easy to do on a laptop). I still bought the same four books and more display folders and it worked brilliantly for me. Never lost a thing, everything was organised.
Get yourself a nice bag too. I received a big Crumpler brand bag from a friend, and it was really nice to carry my stuff around in.
Basically just figure out two things - decide whether or not you need a laptop for your subjects (are you going to be taking lots of written notes in your lectures that could be better organised with technology? If so, a laptop is the way to go) and otherwise figure out if you'll be doing lots of exercises (get a book to keep it nice) or lots of scribbling (loose leaf is your friend) or a combination of both.
