Goodness knows, we of the middle-aged, computing generation could stand a bit more exercise, especially when you get paid to be a desk jockey.
Oh, and this one I actually did buy - today (July 14), it's only $65 at Amazon
Update: Great little product. I couldn't use it under the desk - my knees would have hit it - but I keep it next to my desk in my office and can spend 10 to 15 minutes pedaling while reading a report or article and burn 100 to 200 calories. Easy to assemble, works well (so far) - all in all, I give it high marks.
