12:09 am Eastern time. I just saw this post and checked it out. ATV says there's an update and I'm downloading now. Three minutes left. Not sure what it is, but could be interesting. More to follow.
Just finished download and reboot. ATV now reads software version 2.0.1. I don't see any major changes (not really expected), but my first impression is that response time to button presses is better. Everything seems "snappier".
