Morning all. I'm looking for people thoughts on the macbook air, preferably owners. I'm home in ireland for over half the year and i'm in Birmingham for uni for the rest. I have my sig rig in Birmingham for the uni year and I bring it home during the summer. I'm looking for something light when I'm travelling back to Ireland on my reading weeks and breaks (Ever 4-5 weeks roughly) I'm looking at the air because it's light and i don't need much power since anything stressful will be done on my sig rig or I can use my brothers desktop at home. I have a few questions. Does it have adequate processing power for normal usage? Should I get 8gb of ram? Should I think about an ultra book? Note: I will be buying it from the states if I do buy one.
