Offices vs. Cubes For Developers?

k12boy asks: "The company I work for has just announced that we're going to move our corporate headquarters (locally, but to a new building) and our facilities folks are currently searching for the new space. My intuition tells me that the developers on my team would be a lot more productive if I could give them offices (even shared) instead of the cube space they currently have, but I don't have any data to back it up. Does anyone have a pointer to any studies that prove me right or wrong?" Studies aside, can anyone think of a time that programmers actuallly did work more happily or productively in cubicles? Might there be advantages to more open workspaces compared to closed office doors?
