On my new computer it came with a new swirly logo that pops up hear and there. I started clicking on it an playing with it. What it turns out to be is a google search engine of my hard drive. I use the windows search function relatively commonly, but it still does not do the full job. Once I tried this thing, I am hooked. I am so hooked in fact that I am begging for more featuresl. At a minimum I want to be able to search for text strings that search only for that text string in order.
I heard Matt Cutts talking a lot about Google Gadgets, but was not that interested, because I am so fascinated about Google search.
I really feel like this is one of the most valuable google additions to date. The best part was that it was a surprise to get it, and it was free! Thanks google!
