Preferring OSX to XP is somewhat of a no-brainer at this point, as XP is about 10 years old. A fairer comparison might be the Win7 RC (perhaps, I don't know about breadth of driver support).

OS preference is not primarily dependent on OS age.
But, that being said, I am so used to OSX that I prefer it over windows XP at the moment. But I have recently enjoyed the simple breadth of things I have been missing out on (gaming and game design, add-ons and free apps, etc).
