A new version of Google Desktop for Linux has been released.

<< Feedback from people like you shaped this update. Because many people wanted to search and launch applications, we added that functionality to the product. Desktop for Linux now supports many more image formats and will show better thumbnails for them in your search results. You can also customize the hotkey used to launch the quick search box. And most importantly, Desktop for Linux now searches the content of Microsoft Office documents – our most requested feature. >>

Yay, a few days before Ubuntu 7.10 Gutsy Gibbon comes out.
(And by the way, both are working smoothly)

Still no sidebar + gadgets. I need those..

I don't really like Google Desktop but i haven't tried it in a while. Maybe i'll give it another chance in Gutsy.

P.S. Everyone should try Gutsy if they haven't aren't planning on it already :)

Screenlets does a pretty good job, and devs are working on a project to run Google/Yahoo/Microsoft/Apple gadgets on Linux with a single lightweight program.
