What would be your choice 2010 15'' i5 MBP with Hi Res AG for $1,399 or 2010 13'' MBA with 4 GB RAM for $1,189 I'm leaning towards the 15'' Hi Res AG for a larger screen and I could make some minor upgrades myself. The MBP also can upgrade to 8 GB RAM. Both should handle what I need done so long as they can manage the OS upgrades. The MBP also has FW 800 so I can pick up a external HD that won't be so expensive. The MBA is more portable but the MBP has a larger screen as it will be my primary computer. Am I missing something?
