Desktop Search

With hard drive sizes being so enormous and allowing you to store so much information, I can see that it would be handy to have a search tool that works better than Windows Find, but I really don't understand the rush to get these tools out there. First of all, I really haven't seen much demand for them, and second, based on the Google tool, which is the only one I have used, I don't see any great functionality that I was missing before. Whenever I have used the thing, all it ever seems to find is files from my internet cache. I'm sure they will improve, but right now, I don't see what all the fuss is about.
