At an open-air market near where I live, a man sits all day long demonstrating a kitchen tool that dices, slices and chops vegetables. He must use up enormous quantities of vegetables each day, but he never fails to draw a crowd. As much as Americans love gadgets, we seem even more fond of watching gadgets in action. On Expo TV, you can see almost any kind of product -- from crib toys to home fitness gyms to, yes, slicers and dicers -- reviewed and demonstrated by someone who has bought them. These "videopinions" don't just tell you what the reviewers love or hate about the product, they show you.
