Well, I'll counter-point that I was in a 3-5 person team room for a few years and it was terrible. I've been in an open office for the last 1.5 years and it's been amazing and I've never been more productive. In the team room, no matter what I did, people felt they had the right to interrupt me. In the open office, I put on my headphones and am free of distractions, and people know that if you have headphones on you don't want to be disturbed. So each to their own I think.
