How does an open space office improve vs working in a single office?

For me, it's mainly that I'm happier, more energized, and more focused. I can point to collaboration effects, but really that's less important for my personal productivity I think.

Just to be clear: I'm not saying an open office is right for everyone. If an open office isn't right for you, then you should be able to work in a private space. I'm just asking that you offer me the same courtesy. There's no reason we have to force everyone to work in the same style of office, when everyone has different working styles.
