Now there's an official version of Windows XP that will be able to run on an Intel Mac without an emulator. It's called Boot Camp. This gives me a lot of hope for Mac.

I would suggest the following rewording:
Seriously, why would you put Windows XP on a Mac for any reason other than running apps that are Windows specific?
Discounting that rationale is like saying "Aside from seeing, why do I need eyes? The only reason I can think of is that some people like wearing glasses."
