I made my own standing desk and I've been using it for a year now. I won't go back because just by doing that, I have more energy through the day. Who cares what the flip-flopping WSJ keeps saying.
You are very possibly harming yourself far more with a standing desk than you would by sitting. Sitting is correlated with fat metabolism issues, but standing for periods of just 10-15 minutes is correlated with vascular disease; standing was shown in studies to correlate with increased stress hormones and increased blood density.
You are better off setting a timer and, every 20-30 minutes or so, getting up and moving around (you don't have to exercise strenously; just walking for a couple minutes from one spot to another seems to do it).

This isn't meant as a threat, either: I'd be quite interested in a comprehensive literature review of this stuff.
It reminds me a bit of the brouhaha around barefoot running: some decent evidence suggests barefoot is "better," while some suggests that forefoot striking is really the key. Expert opinion is split.
I always thought the main argument for barefoot running was that it makes heel strikes and other things noticeably unpleasant, thus encouraging proper technique (forefoot striking).
You sound quite certain for what appears to me to be equally ambiguous; Can you elaborate if you have some evidence which points to the hazards of standing far outweighing those of sitting?
