I saw the news today about the revised MacBook Air. The processor speeds on the revised Kaby are very competitive with the MacBook Pro i5 from what I saw on Geekbench. Why pay the premium for a MacBook Pro if the MacBook Air might come close in terms of CPU spec? Simply a matter of having better graphics card, more thunderbolt ports, and minor things like that? Could use some context. Thinking about canceling my MBP order and waiting.
