I'm gonna ask elsewhere, but I spent a few minutes playing with Apple TV, and it seems like, once again, Apple is on the ball with a consumer friendly product that delivers quality.
HDMI output for video, a cross-bar type interface that allows browsing to music, photos, videos, etc. Oh, and component and composite are there for those of us in the stone age.
I know it allows wired Ethernet, maybe wireless as well (for those who care).
The internal 40GB hard drive seem to make a lot of sense for local immediate access storage when bandwidth could present an issue.
I'm very seriously considering picking one up just to play with at my house.
