I started the standing desk around 3 months ago and noticed an almost immediate improvement in my posture and back discomfort. I tried to be realistic and try 1 hour, then 2, then 3. I then moved to getting a treadmill desk at the office: http://bit.ly/nHuCRr now that's baller. You can easily code walking at 1mph, just enough to keep your legs moving. I try to get 1-3 hours a day on the treadmill desk these days.
Some keys to success, make sure your monitor is eye level and you're typing at a 90 degree angle, and get a gel pad to stand on, makes a huge difference.
here are some other desk setups I've been working with http://bit.ly/noPYyY - original makeshift desk at work http://bit.ly/o6vDEi - current home office setup
