I have been at my place for around 3 years, and it was pretty new when I started. I was in an office with one other girl, so when she was speaking, it was usually to me. Now there are 4 of us in the same office, team leads like to discuss stuff with the developers in the office(despite having their own larger offices with tables for that sort of thing). Plus we have more people using my database, so I am getting way more interruptions. I would give my productivity about a quarter of what it was.

Open plan may be better for team productivity, but I doubt it will be 300% more productive.

I personally prefer emails. That way you have something to refer to rather than having to remembered all of the tiny details. Plus we change our mind so often I often can't remember what the final choice was. And tehy don't interrupt what you are doing.
