I bought a 2010 15" i5 MBP last year, which ended up getting liquid damaged after 3 months. Now I have enough money to buy something new. I was going to get the same computer but have been considering a 13" Ultimate MBA with 4GB RAM, 256GB Flash storage, and 2.13GHZ Core Duo. They both are about the same price. My usage is mainly for surfing the net, iTunes, and maybe the occasional game (Starcraft 2). I've heard good things about the flash storage vs. HDD. Will this MBA be a decently fast computer for 4-5 years? Or should I just buy another 15" MBP?
