If you have not yet gotten a Apple TV box, here is a big reason to get one. Apple announces support for watching Youtube videos via the Apple TV box on your HDTV.

Apple will release the Apple TV upgrade next month. I still did not hook up the Apple TV box we used for our Katherine's Gadget Model shoot in April. As I am not into downloading vidz, but watch the occasional Youtube video, this is a reason for me to use the Apple TV regularly.
Apple also announces a new Apple TV model with a large 160GB hard-drive to be available soon.
The 160GB version will sell for $399, $100 more than the 40GB standard Apple TV. Via the Apple TV page.
