I just got the the 13" mba i5/4/256 and am seriously considering upgrading it for the i7/8/256 but then I see that would be around $80 more than the $1399 pro model 13" mbp i5/8/256. Reason for thinking of upgrading is because here and there I notice a bit of sluggishness on my mba and I also want to have it for a few years. I know mbp aren't issue free as there are some complaints here which would worry me if I was to choose the 13" mbp midrange model. Also don't want to lose battery life and portability(I know 1/2 pound) I guess I'll list my questions. 1. Would a jump on the mba from 1.3ghz to a 1.7ghz be that much noticeable than a jump from the mba 1.3ghz to the mbp 2.4ghz 2. Are the issues on the mbp being taken care of with updates? 3. Anyone else recently change from a 13" mba(newer/older) to a 13" mbp? 4. I like the 1440x900 resolution, would it be much sharper running that on the mbp? Or a problem? Please feel free to add any other thoughts to help with my decision thanks.
