TechNet Flash: Preview Internet Explorer 9
While not directly HTPC related, I thought it was news worthy especially hardware-accelerated goodness and potential Media Center integration (ok that is far-fetched).
I wub my Chrome but will definitely be trying IE9 preview.
Check out the new capabilities of the next Internet Explorer, with the Internet Explorer 9 Platform Preview. Find demos of HTML5 and the hardware-accelerated performance with background compiled JavaScript. You can also download the Windows Internet Explorer Platform Preview user guide and release notes.
