A tidy computer desk is a sign of an unsound mind
Everyone comments on the position of my mouse table. When I was on my last job I had a corner desk with a return, and found it to be an extremely comfortable position for using the mouse for extended periods of time. My desk at home is a little higher, so I got around it by putting the mouse surface on drawer slides making it 5 or 6 cms lower, and it just slides away under the desk to give access to the drawers underneath.
You know me too well...

This desk has one of those return thingy's..to the right of my puta.. never use it though. I would find that position rather hard to get used to...
