In a thorough review of the new speed-bumped white MacBook, Macworld notes an intriguing fact: the 2.13GHz model of the $999 entry-level laptop actually outperforms the base unibody model. The magazine's benchmarks show a 4 percent advantage for the new white MacBook over the $1299 2GHz aluminum laptop; the white model even outlasts the next-generation machine on battery life by more than 30 minutes.
Unless you absolutely have to have the new industrial design on your laptop and you're willing to pay an extra $300 for the privilege, it does seem that the new white model is the better buy... for now. A performance gap like this is a strong hint that the unibody models are due for a processor bump sometime soon, if only to restore the proper order of things: faster should equal more expensive. Right?
