you have probably got one already, but in my 3rd year of uni and always used Windows i went to buy a mac and had the same problem. in the end i went to with the white once, saved money, does just about the same, and with the extra money i went on crucial got and extra 2GB ram for £40. and even if you put it in yourself its still under the applecare warranty, which also adds another £50 quid on your bill after the student discount which takes about £100 of the price of that.
