Looks like Microsoft does not want to be left behind in the browser wars as it recently announced the Internet Explorer 10 platform.

The Internet Explorer Platform Preview has been updated. We encourage you to try out the newly added platform capabilities, and report any issues that you find in the Internet Explorer 10 web platform. Note: some features are incomplete or might change later. For more information, visit the IE Test Drive site and read the Platform Preview User Guide
IE 10 preview is available only for Windows 7, and its gonna be buggy, but if you are interested in finding out more and test driving it, then go to:

I won't be installing it, but if you do please drop back in and let us know how it goes.
