I agree with Joel, I've worked in an open floor- plan, individual offices, shared offices, and even one open floor-plan where part of it was an actual store front. For me, happiness and subsequently long-term productivity has been directly correlated to privacy. While I'd never do anything casually I'm an open floor-plan I got successively drained over the week to the detriment of my nights and my weekends, so in the short run I was more productive but I also left those places.
