A:AnswerHi, Tovar007!
The Android TV™ device is designed to lean back slightly on the stand in anticipation of setting it on a low TV rack.
Your line of sight when sitting is 15 degrees lower than when you're in a usual relaxed state. It's considered ergonomical to set your TV at a lower position and tilted back by a couple of degrees. This way, you'll be able to enjoy watching TV programs comfortably. -Sam

A:AnswerIt has Google Assistant built-in, Built-in Wi-Fi, Ethernet, and built-in speakers. Thousands of apps, including your favorite Android games, Sony's Android TV brings you everything in an instant.
