I also like that we each have a whiteboard, plus whiteboards in the "hallways". Anything important tends to go to text, one way or another.
I'm apprehensive about working in an open-plan office, or some arrangement with a shared desk. One concern is constant movement in my peripheral vision. Another is degradation of communication. I like my text. Having something written means that I don't have to ask someone to repeat themselves again. Add to it: Half my team is remote, so no office layout will change how I communicate with them (IM+email).
Then again, I've never worked in an open plan office. Maybe I'd like it, and the things that I see as potential issues would dissolve away...but it seems like a panopticon-distraction fest, looking at it from the outside.
