>I have two of them, one at work, one at home. When I liked the one at home (after two days of use), I requested the powers that be to purchase one for me fat work. It was a PITA to switch keyboard layout between work and home. Glad I got both of them within a week of each other (more than a year ago). Excellent keyboard.

Same here, I have one at work on my primary development machine and the other at home connected to my laptop PC. I knew going in that when I got used to the ergonomic layout I wouldn't want to switch back and forth between it and a conventional one, and of course that's exactly what happened.
