Google has been released their new Web browser(beta) called Google Chrome

Google takes aim squarely at MicroSoft with the release of its new Web browser, Chrome.Initially available for download for Windows Vista and XP, Google plans to expand its Chrome offerings to the Mac and Linux platforms as well. The company doesn't offer any timeline for these versions, though.
Chrome automatically detects the Web browser you're using and prompts you through the process of installation (right down to telling you how to access downloaded files within Firefox, for example). When you first run the application, Chrome imports your bookmarks, passwords, and settings from Firefox or Internet Explorer. It even can grab username and password data, and it automatically populates those fields for you when you use Chrome for the first time to visit a particular site.
