Many and varied, but most importantly because I actually like Windows.

Until today, I thought people like you were the unicorns of the geek world.

That's probably one of the nicest things I've been called after admitting to liking Windows ;)

I use W/M/L on a daily basis. User of all, fanboy of none. No platform strikes a perfect balance for me.

Windows accelerators are pretty good; far and beyond OS X, in my non-expert experience with the Mac. I can't say much for Linux because it's pretty much all terminal :-)

Oh, the Mac mouse acceleration annoys me to no end.

More edits. Actually I can't say that about Linux. It's terminal because it complements my useless cmd.exe in a VM. The Linux accelerators are about the same I guess.
