I just got a walking desk set up in my home office with an old used treadmill and some cinder blocks. It's fantastic. I've tried doing just a standing desk and had a lot of the same problems the author mentions - my legs would get achy and I couldn't get in to a flow. While walking I don't have that problem. In fact I daresay my focus increases while walking. I've done about 50 miles on it so far and I feel great.
