I know how you feel. Whenever I get a new computer, I play for a while with the Windows it came with. But after a few hours or days, I thankfully shrink the Windows down to about a 30 gig partition (if not blow it away altogether), and install Linux. It's like putting an old, comfy coat back on after trying on a new coat.

We don't need OS wars, just like we don't need browser wars.
