I just bought a 2010 Mac air I'm super happy with it! But now my gf steals it more and more so I'm looking at another one lol. Here are the specs: Mid 2009 MacBook air 13" 2.13 core 2 duo 2gb ram 128gb ssd Nvidia 9400 30 cycle count. Are there any problem areas with these? I can get it for 500 good deal? Bad? Any feedback on this model or advice is appreciated thanks all.
