I program all day long and I spend about half my day at a walking desk like this one.

I was distracted by the bobbing up and down for the first day. It was a little less distracting by the second day. And by the third day I didn't even notice it. I was able to get in my regular programming zone with ease.

In fact, I find that walking can often get me focused faster.

But, I am somewhat of a kinesthetic learner. Motion helps me think. So your mileage may vary.
