Popular Science has come out with a futures exchange. It is pretty darn fun. You buy into stock for the iPhone's success, and whether the average gas price will reach $3.50 in the US. It is mildly involving, and keeps you busy, when we all know you aren't (work, anyone?). I would say out of a possible 5 points of genius, I would give it a 3. It shows that it is some what possible to predict the future based on what consumers want.
Apple - If I were you, and I'm not, I would watch this, just to see what kind of demand is to be expected.
