I'm not sure why the thought came up, but I'm thinking back to the time I worked on the Math Department [1] at FAU. [2] While technically I shared the office with one or two other people, they were rare, if ever, there and I practically had the office all to myself.
And it wasn't a small office either—a decent 15' X 30' office, filled with books on every conceivable topic, a real blackboard, beautiful desk lamps (I would often turn off the overhead flourescents and light the office with nothing but the desk lamps) and an SGI workstation pretty much to myself.
Okay, the only down side was the lack of windows. But man, it still was a cool office.
