The 'sealed-box' Mac: Cutting-edge design or planned obsolescence?

Apple unveiled the new top-of-the-line 15-in. MacBook Pro, with its ground-breaking Retina display, a truly drool-worthy laptop if ever there was one. It's fast, powerful and stylish, setting the standard for what a full-featured yet highly portable laptop can be. But that gorgeous package comes with a cost.

iFixit, in its teardown analysis, gave the Retina MacBook Pro the lowest possible score, 1 out of 10, for its almost complete lack of upgradeability. There are no user-replaceable parts whatsoever, including the battery or even RAM, which, in a trend begun with the MacBook Air in 2008, is directly soldered to the logic board.
