Does me too. Now I've been guilty of buying a good name then not knowing how to capitalize on it, but those people who just sit on one year after year and don't develop it I don't understand. A lot of times I've run into this and it was a company that bought all the similar subject matter or single word names and had no intention of selling.
it's because the older the domain the bigger its value. i'm pretty sure that they will sell it if there's a big offer.
