Looking at the rear of the new AppleTV is a study in simplifying and looking forward to the future.
All power is onboard. No need for bricks. With simplified and modern power controllers, this started with the new Mac Mini.
No composite video or audio outputs. Arguably the majority of TV's now have HDMI inputs. Your room pounding AV Receiver probably has 3 of them. They left in the optical audio outputs for purists like myself.
USB Port. Wondering why they left it in. There's no drive, but conceivably you could hack the box through there, or maybe add some kind of external drive?
