The "new" Apple TV is new mostly in name. The box itself is exactly the same on the outside, while and the upgrades that do exist are modest: 1080p support, a new single-core A5 processor, a redesigned user interface, and improved iCloud video support. In fact, if you flip between the two boxes (like I did during my testing), it's almost impossible to tell which model you're using.
Given that the changes for the new Apple TV are so minor, my buying advice remains largely the same. The Apple TV is an excellent streaming-media box, especially for those who already own other iOS devices and are invested in the Apple ecosystem. AirPlay is still a killer feature, plus there's dead-simple integration with other Apple services like iTunes Match, Photo Stream, and iCloud backup of your TV and movie purchases. However, the Roku LT remains a compelling alternative, offering significantly more content sources at half the price, especially if you won't take advantage of the Apple-centric features.
Around back are just a handful of connections, including HDMI, optical audio output, Micro-USB (for service only), and Ethernet. There's also 802.11n Wi-Fi built-in for connecting to your home wireless network. Note that HDMI is the only video connection available, so if you have an older TV, you're out of luck.
The included remote is minimalist in a classic Apple way. It has just a navigation circle at the top, a Menu button (which doubles as a Back button), and a Play/Pause button. That may not seem like enough, but we never felt the need for additional controls. Skipping forward and backward is intuitively done with the navigation circle, and although we thought we wanted a Mute button, Play/Pause worked just as well in every instance we ran into.
Unlike most other streaming boxes, the Apple TV's power supply is built-in, so there's no wall-wart or bulky power adapter. The include power cable also feels a little slimmer than the traditionary cables included with home theater devices.
