I'm a PC user the way I'm a Catholic: I was raised that way. I don't always know why I use a PC, and I have nothing against Macs, but it's what I'm most used to and comfortable with.

I did want to know that when it boils down, for freelance writers, is there a difference between Macs and PCs? How much variation can there be if you're only using Word and Internet and maybe a few other little programs? I asked Gina at Lifehacker for her opinion, and it sounds like there is a slight edge (or that Gina has a slight bias) :

The answer isn't clear, I think it depends on what you want... Macs are more reliable, but they're more expensive to buy and repair. Apple's release cycle is insanely short so you buy a Mac something and a few months later something new is out. PC's are cheaper and you get more powerful machines for your buck (which means you can get a faster processor for less money and more memory when buying PC than a Mac, though some gearheads will totally argue with that and say they're different processors which can't be compared. Fact is, in terms of Gigahertz, you get more with PC's). It's easy to upgrade and replace parts on a PC. Macs are beautiful and more pleasurable to use, easy, and you have to worry a lot less about viruses and spyware. So it's a toss-up.

If you write with Word, either a Mac or PC will do, ultimately. But if you want to love your computer and love working on it (and you do), Mac's the way to go.
