That's the kicker for me - when I talk to people who are complaining about open floor plans, they typically work in a place similar to the one pictured in the article. Now, that's not to say that more space necessarily makes it better for productivity, but it will certainly make some difference (at least, to me). Where I work, we have an open floor plan, and we have a good amount of space around our desks. I personally like it, but I can see how its not for everyone. If I were crammed in a tiny space, I would definitely be clamoring for an office.
