Is typing comfortable with a standing desk? Every time I've used a computer at standing height, it's been a little uncomfortable, but they certainly weren't tailored to my height.
I use this one that I built for $22: http://iamnotaprogrammer.com/Ikea-Standing-desk-for-22-dolla...
Love it. Use it every day at work, and days when I have to sit all day (Traveling, in meetings, whatever)... I feel AWFUL at the end of the day.
