I got a standing desk at work last June.

I got a standing desk at work last June. I purchased it because I figured I could raise it up when I felt like taking a little break from sitting. I anticipated having it in the raised position maybe 10% of the time.

Well, I was completely wrong in my expectation about how I'd use it. Now, nine months later, the desk is in the raised position about 85% of the time. When I'm working by myself, it's almost always standing up. When I have meetings in my office, we all sit, so I lower it. There are also times when I'm doing something that requires ultra-intense concentration, and I will sometimes sit for that work. But, my colleagues often mention that they hardly ever see me sitting at my desk anymore. I've actually considered getting rid of my desk chair (I have an exercise ball that I could sit on if need be).

Two benefits I've experienced from standing up at work: First, I don't get the mid-afternoon sleepies any more. When standing, the 3pm head nods just don't happen. Second, my lower back gives me far fewer problems than it used to. Two years ago, I was routinely waking up in the morning with a sore back. Now, not so much. Sure, yes, it could also be that I've taken up taekwondo in the interim -- that's great for core strength -- but my experience suggests the standing desk is helping as well.

All told, I'm delighted with it. I really do hope everyone who does desk work for hours a day can try it out and see how their body reacts. I suspect a great many people will prefer it for much of their work time over sitting.

p.s., And yes, I realize I'm directly contradicting the article. I feel OK about that because, unlike many of the subjects, I actually do use my standing desk as such.
