I've also been using a standing desk for a while -- maybe six months at this point.
I built my standing desk out of scrap wood, and quickly determined that I wanted a place to put a foot up: At about 12" off the floor I added a horizontal support that I can leave one or another foot on. It makes a HUGE difference for standing.
I also have a drafting chair that I CAN sit in if I want to, so I'm not completely tied to standing if I'm tired. My most productive days are certainly the ones where I stand for most of the time, though.
Great point on the low foot support. I've been nearly subconsciously putting one foot or the other on objects underneath my standing desk. Breaking symmetry and having multiple positions to stand in is certainly useful.
