My sentiments exactly. Although I'd add it's a good idea for companies to set aside some closed offices for times when people really want to avoid distractions and/or have some permanently set aside for those who really can't work in an open office environment.

I just can't imagine going back to cubicles, or isolation. The distraction I get is more than made up for by the camaraderie and communication that naturally occurs. Although to be fair I've never been in a seriously dense open office environment -- that might change my perspective.
