Workout in bed?

As a college student (better known as professional napper) I was quite interested by this article. After all, I did just spend the first half hour of my morning coaxing myself into lacing up my running shoes. Gosh, why do that when you can run in bed?

Unfortunately, the idea for the adjustable bed with treadmill attachment isn't quite made for me. The invention of a surgeon in Nebraska is to help obese patients fit in workout time with little outside assistance.

I wonder how much one of these would cost to place in a college apartment?
