I have a TrekDesk in my office at the law school at which I work. It has become somewhat of a tourist attraction among the students, staff, faculty and lawyers who are on campus. I did 8.3 miles today while writing memos, talking to students and using the phone. Once I figured out how to best place everything on the desk to suit my particular needs it has been easy to use. I feel guilty getting off of it to go to meetings. I have had it a couple of weeks and am quite addicted to it. I am betting that people who have seen mine will end up buying one too. Lots of sedentary lawyers out there....
