I don't particularly mind that people see my monitors. If you work in a decent place, no one would care if you read some news once in a while. If someone spends the day idling, then it's noticed anyway.
Once in a while I get a sensitive or confidential email, but that usually happens when the computer is connected to a big screen in a conference room full of people anyway...
I DO mind not finding anywhere to sit, not knowing where people are when I want to talk to them, not having two or three huge monitors to work on, and not having my Model-M to type on...
Personally I do mind, not because of fear someone catches me procrastinating on Hacker News (most people in my company wouldn't even know what it is) - I simply can't focus with other people close behind me. It's a weird kind of stress.
I guess there are some stools and tables available somewhere, and technically you can sit on the floor I suppose, but people that are late more or less have to go home again.
They are kind of in a downwards spiral anyway, so maybe it will sort it self out.
