My brother in in the New York area for a trade show. When I was driving him to the train this morning, we were discussing the uses and uselessness of various PDA-like objects. He has a pocket PC and was telling me what he used it for, hence the following annecdote:

John was in a Best Buy trying to buy a computer cable. The salesman directed him to the cable he needed. The price was $40 which seemed like too much for just a cable. John whipped out his pocket PC right there in the aisle, typed the info on the package into a technology search engine, and discovered that the cable in question could easily be had on the web for $10. He showed the web price to the salesman and said, "I know you guys have to make money, but you charge four times as much as this place on the web, so I think I'll buy it from them instead." (Knowing my brother, he probably suggested that this was not what he called a Best Buy.) Then he walked out.

(Cory or somebody like that is going to say, Oh, I do that all the time.)
