Apple's 15" Ultra-Thin Notebook

Apple's 15" Ultra-Thin Notebook Due in March 2012, supplies are limited and prices have shown a substantial increase in recent weeks.Upstream suppliers of Apple have recently started shipping a small volume of components for a 15-inch ultra-thin notebook model from Apple in November and the device could be either MacBook Air or just a thinner MacBook Pro. The new MacBook is expected to appear as early as the second quarter of 2012, according to sources from the upstream supply chain.
Digitimes is unclear if the parts are intended for a 15" MacBook Air or a thinner 15" MacBook Pro. In July, we reported that Apple was finishing up work on a new ultrathin 15" notebook, and at the end of October, it was rumored that new machine was nearing production.

It seems likely that a thin 15" MacBook would use a SSD rather than HDD, similar to current MacBook Air models, and would forego an optical drive. The MacBook Pro line was refreshed earlier this fall with minor processor, graphics and storage upgrades.
