I agree... it seems like the fixed office could become a relic of the past. it used to be important that you were generally in your office... so people could find you or reach you on your extension, but with chat and email.. it seems less relevant.
More importantly, with the portable work stations available today. It used to be a big event to move desks. Now you can work in another floor, no need to take your bulky computer and all the cables and network configuration with you.
