According to our pals over at Macrumors, Apple is working on an ultra-thin 15-inch Macbook. It’s not clear at this point if it will adopt the same specs and limited feature set as the recent released Macbook Airs, but the site says that the laptop is in the late testing stages at Apple.
In the past Apple has indicated that it is looking to move away from all things spinning (hard drives and optical drives) inside of their machines. So we see the chances of this rumor as being true pretty darn good. Macrumors also says that Apple is working on a 17-inch version, though there doesn’t seem to be any indicator as to where that is in the development phase.
On the other hand, Apple just released the brand new Macbook Airs. So it begs the question why they’d release another laptop with an almost comparable feature set, but with a larger, more popular screen size. However, Apple has long sold the Macbook Pro in 3 different sizes (13″, 15″ and 17″), so the move wouldn’t be all that unorthodox.
