Application envy?? what's on your Dock?

Besides liking clean, that advice is what Tech Support told me at my last job. And as we had PCs, I used to do that thing with the cache to get files back where they belonged. It looked like a Pac Man screen with the 'unneeded' files being eaten away. It's one thing I miss on my Macs. I like to see the process when I'm clearing my cache.
