42. Been in an open office for about 15 years now. I think there are pros and cons but I prefer private office or a cubical with some privacy. I agree with you that OO enables communication, absolutely the case. I can see if people are here I need to talk to, walk over and talk to them in person (which I prefer). However it's a mixed bag, if you are the person being interrupted all the time to talk about something. There's an expensive context switch.
