Hi, i purchased a 3.06ghz 2gb 24" iMac in October for uni - and i'm honestly thrilled with it. The only downside is - it portable (i know - pretty obvious but still). I've been looking at saving up for a some form of macbook to take around uni - to lectures etc. After browsing the internet i've found that it wouldn't really make much sense to pay around £1160 (with student discount for a standard 15.4" macbook pro) and that it would probably make more sense to get a 13" white macbook. this was before i discovered the price of 2nd hand macbook airs - which is not too much more than the 13" macbook. i have looked in other forums and read the ups and downs of the macbook air etc. but still which to choose, as i do have a powerful iMac with a large screen.
