I connected the ATV2, and, am so far pleased. I put it to "sleep" and noticed the next day "netflix" required me to sign in again. A real pain because the "keypad" is so poor (slow). Is it necessary to put the ATV to sleep? Is there any harm in leaving it on? There should be an APP for ATV which would make the whole thing more intuitive.
TV 2 to never sleep. I don't like having to wake it up every time I go to use it or want it available for Airplay. I don't think the new one draws much power when it's not in use -- unlike the original it barely even gets warm.
