An update to Apple's MacBook Air may be pushed back several weeks due to delays in the ultra-low voltage Core i5 needed to drive it, rumors circulating today suggest. Since Intel has allegedly had to push back the 1.06GHz i5-520UM versus its full-power counterparts, Apple in turn may have to either avoid updating the extra-thin notebook at the same time as the MacBook Pro or else put the ship date in the future.
