I just dropped $1800 and change on an iMac, which really doesn't have any more mojo than an equivalent PC.
If I need support, someone will say: "How can I help you?" no matter how inane the question, instead of (Linux) "RTFMNoob" and (Windows): "Google, install driver, visit MSDN, etc.".
The difference (in my mind) is that I didn't buy a personal computer, I bought a Mac. I didn't buy what I needed, I bought what I want.
