Google has released Google Desktop 3.0 beta, which includes several new features. Three of the new features Google considers 'major' enhancements, but several other new features requested by users bolster the utility of the program.

User of the GoogleDesktopSearch since its very first launch, I won't upgrade to this version. I don't see really innovative new features. As for the "search across computers", although it can be disabled, it makes me not wanna try this version. I don't want Google to have all my text documents stored on their server! We never know what can happen.
