I think NVidia pursues these kind of things to raise their stock price. There is no way they are making a profit with this product, but it gives them something to show off and reinforces the idea that they are the leader innovating new technology. Cuda, PhysX, 3D vision, all of these projects lose money but they make NVidia look better to technically ignorant stockholders. When you see these grand web pages on NVidia's site talking about some new technology, it isn't aimed at the consumer. They are courting stockholders and potential stock buyers. After thinking about it, I really believe the decision to pursue these things was based on the desire to raise stock price even though it lowers profits. It's not really a good or bad thing, but it would be a mistake to get suckered into technology the proprietor themself doesn't even believe in.
