Another anecdata: I'm in an open office right now, and the area that I'm in could ostensibly be considered to be a "cove", with about 6 people. I hate it. I'm not on the same calls, so people being in calls messes with my flow. They're not on my same calls, so I either have to move to a hot and sticky phone booth, or leave the building entirely (I've taken a few calls in my car) since I work on projects that aren't ready for the office rumor mill.

I really miss my cubicle. I could stand up and have a conversation, or sit down and be in relative peace. The sound and visual isolation offered by those fabric walls can't be overstated.
