For all the folks (including me) who questioned Google's ability to ship software, you have another thing coming. Google Desktop (http://desktop.google.com) is now out of beta. Among the new features, you have full-fledged API support (which is really cool), a floating box on your desktop where you can search from and Thunderbird support. See http://battellemedia.com/archives/001305.php for more
[Update: This is why I love Google. On their submissions page, they have a text box for developers to specify Easter eggs.Awesome!]
