With the Apple TV 4K, Apple is trying to do more than just provide you with a gadget that can stream Netflix or iTunes Store movies in 4K.
The Apple TV 4K combines an app store, single sign-on authentication with cable providers, Siri-driven search, and a centralized TV app to unify your TV viewing experience whether you’re a cord cutter or just looking for an over-the-top (OTT) addition to your cable subscription.
The previous Apple TV had similar goals, but the new model adds a much faster CPU, long-overdue 4K and HDR support, and tvOS 11 (which is also available on the previous model).
The new Apple TV is identical in many ways to 2015's model, so we'll focus mostly on the differences and the big picture of what it offers to your living room.
The most notable physical changes are a slightly raised platform that provides ventilation for heat management and the removal of the USB-C port on the back.
The remote has five buttons: the menu button (which usually ends up working like a back button), a play/pause toggle, a Siri button, an up-and-down volume control, and the TV button.
