According to this article in the NY Times, Google is planning on introducing a desktop search tool for searching personal files and text. I have been trying out X1 Search recently. Its a great idea, but the X1 interface is clunky and a bit of a pain. Perhaps Google will have something more intuitive with similar capabilities. It will be interesting to find out how they plan on addressing privacy - Google ads next to my personal files would be a little concerning, since this implies that some aspect of those files are transmitted to Google so that an appropriate ad is selected. Granted, its unlikely Google can or will read every file indexed, but some form of summation will be needed. Of course, Google hasn't yet even officially announced the product, and if it is real might even come without ads, so no need to panic yet.
