Anyone have success reducing the number of hours sitting down while still hacking just about all day/every day?
It's better to have something that adjusts easily (like a counter-balanced monitor arm and keyboard tray).

The main downside I've seen is that greater mobility makes the kitchen (which is only 15 feet away) way to easy to get to. I think I've replaced the extra calories I burn with more snacks.
My desk is an old coffee table top sitting on my keyboard stand (as in musical keyboard). I also have a stool for when the feet get sore, but I try not to use it too much.
