My experience with PCs is not good.
I worked on a mac for seven years before coming to work on a PC at my current job. Before taking this job, I talked to several designers who were like, "Oh don't worry. The only difference between the PC and the mac are the keyboard shortcuts." I thought about it and decided that it wouldn't be a big deal. Boy, was I wrong. I work on a brand new Dell all day and have problems all the time. I've been here for three months and already had IT come and work on it three times. I have a G4 (currently six years old) at home and it blows this Dell out of the water. It's the biggest piece of junk I've ever worked on.
Windows was designed with professionals like accountants, lawyers, etc. in mind. The interface is just horrible (what's with the big, green, honkin' "start" button anyway?). Macs were designed from the ground up for creatives.
Maybe it's Dell that makes bad PCs, I don't know. Then again, my first computer in college was a PC, and I had major problems with it also. I personally would never buy one.
My 2 cents.
