It was unclear to me whether you're saying you don't want to use non-Apple hardware, or that you don't want to use Windows, or whether you're referring to a combination of those two.

Though Apple continues to use 'PC' in their marketing, it's an obsolete term. Macs are running on the same hardware these days, and you can run Mac OS on 'PC' hardware. You can run Linux on Apple hardware, and Windows on Apple hardware. So, it's a bit muddled.

I assume by 'PC' you mean 'anything besides OSX on Apple hardware'. Okay. Personally I also run Linux on my MBP... not sure where that fits in.
