The desks at my work are on hydraulics, so they can be raised or lowered at will. It's great to be able to raise your desk and stand for a while after sitting for a couple hours, but I wouldn't want to have to be forced to stand all the time.
The desks get high enough that I can push my high-backed office chair underneath it, and low enough to get probably two feet or so off the ground. It's a great compromise between having to sit or stand the entire day.
