Word from Asia today is that the 17-inch MacBook Pro, which conspicuously lacked the aluminum update its smaller brethren and cousins received earlier this year, will finally receive its refresh at MacWorld—with a twist.

The big news isn't the aluminum unibody construction—it's that the portable rig is getting a slimmer, more efficient battery. But, and this is a big (unconfirmed) but, the battery will apparently be inaccessible, a la the iPhone and iPod. What's the deal with that?


Expect more at MacWorld, which may or may not have big or small announcements of any kind. [9to5 Mac]
