What does the presence of iTunes have to do with the ridiculous suggestion that you can only "screw around with iTunes" on an iPad? The logic of your and greedo's replies boggles.
Per the article, the new MBP actually renders at double the scaled resolution (so 3360x2100 for 1680x1050) and then downscales that to fit 2880x1800. (See the screenshots.) It shouldn't look blurry at all. In fact, it should look considerably better than a MBP with a 1680x1050 display.
I was thinking of having stacked mirrors, the way tractor trucks do. But your comment made me think: is there a way to have a flat mirror turn transparent, revealing a curved mirror behind it? You could activate the transparency just by using your turn signal.
At any rate, jrockway is a known troll. Should've known better than to enter this fight.
