I work for the big G. and I work from home. There's a couple hundred employees that work full time from home, a minuscule amount in comparison to the work force.

I travel to the office every two quarters and I usually get nothing done (meetings, interruptions, etc...)

VC, chat and email makes it possible to do work. Folks saying that they can't, err, "ideate" when they're not together making noise and preventing other people from working just don't know how to use the tools they have.
