Just plug “compare prices mac vs pc” into Google and see for yourself.
I’m not going to do your homework for you.
Okay, I'll follow your instructions. First hit, About.com article. First article, "Common Myths About the Mac." Fourth item, "Myth: Macs are expensive. Fact: Apple hardware and software offer tremendous value." Then we have several old comparisons (not a good idea to compare over a year ago in the computer business).
Your Google idea wasn't too useful. So show me, similar form factor, speed, features and software load.
