Ouch. Those numbers below have to hurt if you are in the market for a new high end MacBook Air. Macworld tested the new machines and found the high end 2.13GHz MacBook Air didn’t perform as well as the previous high end 1.86Ghz machine with the same 128GB SSD. In fact, to them, it was noticably slower.
A lot of things could account for the speed decrease including: battery mangement, cheaper laptop parts, testing methods, etc. As I said in my Computerworld column when the Air was released, Apple is making significant sacrifices to make this machine razor thin. If the specs above matter at all to you, you may want to look into a 13-inch MacBook Pro. That being said, would it be that hard to add a 4GB RAM premium option?
