Number one safeguard against any type of malware is being a smart, educated user. If you know what your doing on windows, its never going to be a problem. The last time I got a virus was on my old desktop, was when the computer was still shared in the household. No problems since then (yes, I have a AV scanner, but its never caught anything, I use clamwin, btw).
I've been thinking of buying a mac mini (and then installing winXP on it) solely because of it's small size, you can't get that kind of hardware outside of apple. But that'd be about it.
Also, I have an ipod photo loaded with this:

That made it worth carrying around.
Now with 50% more lol, 50% more win, and 100% phlail.
