The reply I've always heard to this is: "Then is an empty desk the sign of an empty mind?"

I do believe that you've picked up what I put down.

Seriously though, my desktop is essentially bare. I like the space to spread my arms out as I think, and I find that a large clean surface allows me to concentrate better than a desk full of books, knickknacks, and office supplies does.

Yes, me too. People have mistaken my cubicle for an unoccupied one.
