The guy I share a cube with has the loudest keyboard in history, or at least for me. Doesn't seem to bother anyone else. But it sets my teeth on edge.

So much so that I had to dig out my old noise cancelling, over the ear things. Now I can't hear anything else, but hey! :-)

Actually, I found the sound to be comforting. I miss working in an office with a team on site. Of course, I still can't go hang over their cubicle and ask them a technical question, but I only expect so much of that site. ;)
