I can't live without Expose. I often find myself reflexively squeezing the mouse when I'm on Windows, and then experiencing disappointment when Expose doesn't kick in. "Oh yeah, I have to use the stupid task bar."
LOL! Me, too. I have my expose set up to the hot corners and find myself doing that when I'm testing on my PC. Glad I'm not the only one ;-)
Speaking of expose...it really impresses co-workers when the see it. ha.
