Microsoft has announced the availability of an Internet Explorer 9 "platform preview" at Tuesday’s MIX10 keynote address. Developers and the general public can get their hands on the IE 9 platform preview as of Tuesday.
The preview of Microsoft’s newest Web browser is accessible at Microsoft’s test drive site here.
The IE 9 platform preview isn’t a fully functional browser or even an alpha version. It lacks an address bar and many other common browser user interfaces. Microsoft is releasing it to get feedback from developers, and the company plans to release updates of the platform every 8 weeks. Users can run the various tests prebuilt into the platform preview and compare those results with the test performance of other browsers.
