Mac Book pros are not gaming power houses. They shine as content creation tool for people who actualy need a reliable work horse to get paid. It
's not somthing a young adult that works at a meager part time job would understand.
The 15" Mac Book pros have been the high end model and is no slouch for games. however a gaming PC could be build for far less. But that's not the point of the Mac book pro. It's an elegant computer that compromises nothing. It's lighter, faster, and sleaker than any PC laptop availible. Most PC laptops have intergrated Intel GPUs. The PCs that do have anything faster than that are thick, ugly, and have poor battery life (Alienware).
it an expensive laptop but it's price is actualy quite competitive with high end PC Laptops which can't match Mac Book's sleek design. ultra book PCs are all the rage since Mac Book air stole the show over 2 years ago. They are very under powered and come with a limited version of windows, Windows 7 home premium. Air comes with a full fledged OSX 10.7 (launch stock) or 10.8 (new stock), minus all those annoying crap-ware the OEMS put on the PCs.
With Windows 8 stinking up fouler than Vista, Mac can claim even more marketshare.
