Dear All, I understand that the MBP is more upgradeable than MBA, and with the full upgrade, MBP always wins in terms of performance. But with the spec as is below, how would they fare? MacBook Air 13" (mid-2012) 1.8 DC i5/4/128 MacBook Pro 15" (early-2011) 2.0 QC i7/4/500 Since MBA has the SSD advantage, it may actually "feel" faster for normal operations, right? It would be appreciated if someone can actually compare the two models directly, either by benchmarking or real-world experiences. Also, despite the physical size differences, the screen resolution is the same. Would MBP 15" still be better in terms of the screen size/work efficiencies?
