Nowhere is this more evident than when you want to do comparison shopping on an expensive product like a camera or a car. I am actually in the market for a new car right now. I know pretty much what I want. But trying to figure out which product is the best fit for what I want is a nightmare. I go on a manufacturer's web site and it's all marketing. Trying to extract technical details is a chore, and trying to figure out the actual differences between different models and trim lines can range from a nightmare to downright impossible.
