hi, I wanted to ask you guys if it is a wise decision trading my MBP for a MBA. these are the specs: MBP 2.16ghz core 2 duo 120gb hd 2gb ram ati x1600 128mb for a MBA 1.6ghz core 2 duo 2gb ram 80gb hd the reason why i'm thinking of trading is because I don't really use or need the ATI x1600 since i do not play games on my MBP, for that I have a PS3. My main tasks are websurfing, mail, itunes, iphoto, adium, ical, skype, ichat, iwork and vmware for windows. sometimes but not so often I use aperture, photoshop CS3 & idvd & Imovie. will the MBA be able to hold up with the tasks i do?
