The new high-end MacBook Air is paradoxically slower than its predecessor, a review of the system is said to expose. While the updated low-end Air has been made faster, as expected, the new 2.13GHz high-end is actually said to score lower on tests than its older 1.86GHz equivalent. The last-generation model wins out in 11 of 18 Speedmark tests, for an overall score of 179 as compared to 175.
