Apple has started shipping out the new MacBook Air to its buyers. The revision of the MacBook Air includes the new NVIDIA GeForce 9400M as well as a choice of 1.6 or 1.86GHz processors. People who have already received them are reporting they notice a noticable boost in performance due to the upgraded GPU, which takes a lot of the load off the CPU. The MacBook Air is in a tough spot now that the new MacBook is even that much thinner. It’s hard to justify the price difference as compared to the new MacBook considering specs and the new aluminum casing. The MacBook Air has really become more of a niche product than even before.
