Hi, I am a uni student seeking advice on getting a macbook air. My uni is about 1.5 hours away from my house, counting the bus trips and train rides to get from one side of the city to the other. I have a Toshiba A300 with an Intel Core 2 duo T9300 @2.50 ghz with 4gbs of Ram. Unfortunately the laptop weights close to 4 kilos and isn't worth taking to Uni. Should I get an MBA for the portability? and if so, with which processor? P.S. I am a Law/Arts student so most of what I do is research/online based so needing to use a CD drive is not necessary, gaming isn't a priority and I really need something portable which isn't a windows based system!!!!!!!!
