...and also obviates windows focusing problems. I just upgrading all my HTPCs to the Windows 8 consumer preview today. It's been a great decision so far. I sometimes have issues with windows minimizing, losing focus, and switching applications (in Windows 7), which can be extremely frustrating and hurt the WAF factor. With Windows 8, you simply hit the Windows key, bringing up the metro interface which you can navigate with up, down, left, right, and enter. There you can launch applications. Metro also looks great from 10 feet away.
If you use a harmony remote, you can map any key (using MCE keyboard as your device) to 'Start,' which activates the windows key.
On top of that, you can use the beautiful metro apps, although some may require a mouse. I can activate the weather app with my remote for instance.
Anyways, I just thought I'd spread the word. It's been a great experience so far, and I look forward to seeing more metro apps. Keep in mind the consumer preview is not a finished product, and your install will expire next year (although I'm not exactly sure what that entails).
