Another reason why SE makes me scratch my head. Pretty much every single college student uses a Mac
Errr ... ya!
I went to York University in the north end of Toronto. When I started, I had a white iBook and I was the only one. By my last year, I had upgraded to a powerbook, and EVERYONE had iBooks and never MacBooks.
Look around a university today and you see Macs EVERYWHERE. The same demographic that has the money to send their kids to school (I.e. the half of the student population that isn't on financial aid) also has the money to buy them Macs, and they do. Whether it's because they're easy to use, virus-free (mostly), or just fashion statements, they sure are everywhere. My sister goes to the University of Western Ontario, and everyone there has Mac laptops, too.
The current line of MacBooks are due for a refresh. Once that happens, compare them to PC laptops in the same price range and you'll notice that they actually aren't that expensive. The mistake most people make is to compare a $1000 MacBook with a $500 PC and conclude Macs are overpriced... Yet the PC laptop they are looking at has a crappy battery, low-res low-quality screen, is large, heavy and clunky... and the Mac has a 7 hour battery, a ULED display, weighs 4.5 lbs., etc. PC laptops always boast the size of their hard drive and the amount of RAM in them as their biggest marketing features. Those things are ubiquitous. But go to your nearest BestBuy and listen to a salesman sell an unknowing person a laptop... and listen to the poor people ... "Honey maybe we should get this one. The salesman says it's good and it has twice the memory of the Mac for half the price!!"
But I digress.
On topic - Mac users can effectively and completely turn their Macs into PCs with Bootcamp. If you want PC gaming, it's the only way to go. Even parallels 5 is not going to give you the graphical power you need. This isn't an 8 year old game like FFXI.
