So, the new unibody Al Macbook has a 2.4ghz processor, two gigs of ram and a better video card. I mean new. As in, purchased TODAY. How come my 2.0 dual G5 with 3 gigs of ram plays the new South Park episode just as fast? And how come it glitches? I just don't get it. I sold my beloved PB 12" that was about the same?
