Apple's Mac OS X had a good year last year, according to Net Applications. Market share for OS X climbed to 7.31% for the month of December, 2007, up from 6.38% in February, a 14.57% increase. How about the Windows OSes? Why, they're at a paltry 91.79 % of the market. [Net Applications]

As for aftermarket parts, I wonder if you're referring to those shitty chassis lights or useless spoilers that adorn many a front-wheel-drive monstrosity with coffee can-sized exhausts pipes. Surely they're superior to a bimmer, because you can add all kinds of crazy shit on it.
But then, you can do that for BMW's as well, can't you? :P
