Now there’s Google Desktop 4.5, featuring a Sidebar with a new look. The new Sidebar is transparent, so it fits seamlessly with your desktop environment. Gadgets that fought for attention now look right at home, and content-heavy gadgets get new frames and icons that make it easier to tell them apart. All of this leads to a better place to find your email, news, feeds, stock prices, weather and other essential information. And this version is compatible with all of the latest software including Microsoft Vista, Office 2007 and Mozilla Firefox 2.0.
