i'm doing b arts/b laws and from what i have read it would probably be better to use a 3-5 subject notebook for ur lectures - and maybe have a folder for each subject back at wherever u are staying. I'm thinking about using a notebook - or lecture pads and having a folder for each subject back at my room (someone suggested that on the UNE forum)
A usb key would be advisible - especially if u are going to use the uni computers.
If you dont have a laptop - it would be totally ur choice to buy one now or use the uni computers.
I have a laptop and whilst i will be using it an uni - i think getting a desktop computer would be better - for one they are much easier to upgrade (or get upgraded if you aren't techie). The thing with laptop computers is that whilst the are portable - if you dont need to carry it from one place to another - desktops would be better as you can get a notebook computer fo one price - say $2000, and u can get a desktop computer for $2000 as well - but the desktop would have better stuff - more hard drive space, better graphics, more RAM etc
HOPE THIS HELPS!!
