Oh I wish I had one of these in my living room. I'm like half the population -- my treadmill is a very expensive piece of furniture to hang my laundry. Now that I think about it, so was my Nordic Track. And the bicycle. And don't forget the eliptical. But this machine I could go for! Cornell University uses the ice treadmill to train and condition their hockey players, male and female. The treadmill apparently costs up to $100,000!
