"Beats the alternative"
Seriously. Go to circuit city and look at their computers. Compare the price points to the hardware you get. PC games are still coming on 4-5 CD's, because PC manufacturers are too cheap to put in a DVD drive (all macs come standard with one) Okay, so you can get a cheap (but less hardware specs, etc.) PC for exactly what its worth: cheap. Or you could pay more for a Mac and get a totally great computer that, considering what it comes with, is a bargain. Plus they look really sexy.
Don't even get me started with OSX vs. Windows. 🙂
