In general, I'm a big fan. I probably go back and forth between sitting and standing every three hours or so. I don't think I have worse concentration while standing unless I've been standing for awhile and my feet are staring to hurt, which makes me a bit more restless. Another thing I've noticed is that people seem to find me more approachable when I'm standing. They seem to strike up conversations more often, whereas when I'm sitting I must look like I'm working hard and shouldn't be bothered. Overall, I'm very happy to have one and would recommend a standing desk to anyone, provided they have the option to sit as they please.
