Mac vs PC: Hardware and Software
I hate to sound like a Mac fanboy but, you really get what you pay for with computers these days. If you look at similar desktop and laptop PC solutions, you're going to save maybe a couple hundred dollars and have sub-par hardware that doesn't perform as well with the software and possibly uglier. Sometimes you'll end up spending exactly the same amount or more for the same hardware and still have a drop in performance because the software you're going to be using isn't tuned with the hardware like you get in a Mac.
