They're all based on x86 architecture. The only difference between Macs and everything else is that Apple made an operating system for people who can't be bothered to learn how normal ones work and then started a cult to proselytize it for them.
If my virtually computer-illiterate brother can work a non-Mac computer, then it's a non-issue.
Fuck Steve Jobs. Hate he died, but I wish his bullshit had died with him.
