Low supplies of aging Apple models have traditionally indicated a hardware refresh, and the latest herd to run thin is the great wild MacBook Air. Few retailers have any, and those asking for resupply are being told not to expect any until the week of October 12th at the earliest. October is one of the several months in which we find Apple activity, so it’s not such a far-out idea.
Rumors from a couple months ago put the new Air at a petite 11.6″ and have it even thinner and lighter than the current model. That falls much more in line with my idea of an ultraportable; the 13.3″ form factor just isn’t really any smaller than a MacBook in many situations. an 11.6″ Air might even be something I’d be into, and I trashed the first one.
