I do my web surfing, email, and site updating from my 1200 power tower when I'm home.
I've used my machines to emulate various lab instruments and PBXs for work. I've also used the higher end ones to process VERY large mail lists and merges.
Right now I'm just fiddling around with some ideas for some new business software.
