hello, i am about to purchase a mac laptop but dont know which one to buy? my options are the updated macbook 2.4ghz 160gb ,2gb RAM or a 1.8Ghz 80Gb macbook Air. the reason for my dilema is money and computer performance. i can afford the MBA but would rather not pay more if i dont have to. Also i guess some where along the line i am going to need to buy a superdrive and time capsule for the MBA ( 80Gb- not enough!) i only really surf the net, watch movie trailers, i-tunes and occasionally watch a DVD. will the MBA be able to cope with multi tasking net surffing, i-tunes and some MINOR video editing. im just lurred by that slim sexy MBA..... is anybody else in the same boat or have any advice they might offer?
