Are you saying that we should buy KTMs?
In this day and age, I don't necessarily think a chair is a HUGE limiting factor. We have a great surgeon who works on the same floor as I do at Cleveland Clinic....he's in a chair. Has this contraption on it that with his arms can jack himself up almost to standing height, effortlessly. And the guy performs surgery everyday with people laying on a table. And he somehow construes himself to get into the right position to cut!
