I switched to a standing desk after developing a bulging disc in my lower back (crappy!)
It's great until about hour five or so, at which point my legs and knees start crying uncle. I've found that I can last longer if I sprinkle in some sitting throughout the day, during lunches or meetings, and I can go even further if I stand on a foam activity mat.
I think that taking frequent breaks to walk is the best way to get a little relief for the legs and back, and some exercise, at the same time.
