Well, the setup is pretty normal. I'm in a "normal" cubicle, using a standard keyboard, and a couple of 21" monitors that have been raised a few inches. When I squat, my arms are raised higher than there are when I am seated, but they are still at an angle that is reasonable to maintain for 15-20 minutes at a time. The monitor height is actually better when I'm squatting.
I will note that in 15 years in the industry, I've not had any major ergonomic issues (some of that I attribute to rock climbing), so I'm certainly not suggesting this particular setup for everyone.
Ok that makes a lot of sense. I'm going to assume you're squatting in a chair as well. That or you have a ridiculously long torso. 15-20 minutes seems kind of a short amount of time compared to standing though.
I think you should stress that latter part more actually. Being healthy isn't just what a person can do in one area but in all areas.
I have also done this for many years at work. Co-workers generally referred to this position as 'the vulture' which upon reflection, sounds a lot better than 'squatting'.
