A second, even more bleary-eyed post. I can't bring myself to post in that OS X thread since that's a whole different kettle of fish, but who out there's running Linux with Compiz? I just plonked it on my Fedora Core 5 box and I'm loving it.
Tying the scale plugin (equiv. to Expose for OS X) to one of my spare mouse buttons has increased my productivity and satisfaction by 41.99%! (I frequently work with up to 16 windows open (and a few more on the other virtual desktops), and taskbar-on-the-side is the only way to cope on XP)
*rave, rave*
edit - IMO, Expose is the Mac feature for other OSes to copy this year. Looks like Vista has done a poor job of it, though.
