Those lucky (and sadistic) ducks over at iFixit have taken their brand new 17-inch MBP and torn it down with their usual gusto. As expected, the layout and parts are much like its 15-inch cousin but bigger, and of course the much-advertised battery is different. It was removed like any other… not sure why Apple made such a big deal about it. It’s 12820 mAh, which is a grip — for comparison, my G1 has a 1150 mAh battery.
It’s pretty much as advertised, but if you’re planning on swapping out your hard drive or whatnot, this is the best guide you’re going to get.
