"I used to think that I had a sedentary desk job, until I realized I was hauling booty through the universe!"
This setting is pretty much exactly my old office at work. There's my Mac Pro (ok, it's not mine) and 23" Apple Cinema Display (which I want to steal). My workstation had those modular cubicle walls/shelves/table setup, except it was about three times as large as a typical cubicle. I called it my luxury cubicle.
For you sciencey-types, I calculated based off an 8 hour work day, and this.
