I don't consider a 4-person office to be an "office"; that's "open", to me. Google does have lots of meeting rooms and the like, so as I understand it, most developers can find a private workspace most of the times when they might need it. So, it's probably not awful to work at Google.

If facebook is even more "open" than Google, I'm amazed anybody ever gets any work done, but obviously they do, so I may just be more reclusive than most tech people when I work.
