It's been a while since we've seen a substantial refresh of the MacBook Air, and while there's one pegged to land tomorrow, it won't be a substantial one either. Instead we're looking at a slight update, with Apple swapping out the last-generation Intel Haswell processors for the current-generation Intel Haswell processors. Yes, it's a mammoth update.
According to 9to5Mac, the update brings the SKU for the Air up from MD760LL/A to MD760LL/B. Typically the /X updates are relatively minor spec bumps. In this case, it's a slightly faster set of processors, and possibly a rejiggering of the storage options.
Update: 9to5Mac now has the specs for the CPU bumps posted.
The updated MacBook Airs are reported to be arriving in Apple Stores tomorrow. Is anybody going to rush out and buy one, or are you more interested in the inevitable overhaul that will bring along a high-density Retina display like its bigger brother the MacBook Pro.
