There’s only a single MicroUSB port on the back of the disc that you’ll need to connect to either your TV’s USB port or to the wall using the included wall adapter, and a single button that will factory reset the Chromecast if held down.
(The exact dimensions, in case you need them are 51.9 x 51.9 x 13.8 mm.) If you’ve seen a Chromecast in the last few years, you probably know what to expect here - a small disc not more than two inches across that can covertly hide behind your TV. It also includes a new remote and 4K capabilities, though it will set you back at least $179 / £169 / AU$249.
On the software side of things, Apple has opened up its TV app store to third-party developers, making it a bit more well-rounded than the Chromecast. the Apple TV 4K: the newest Apple TV 4K, like Amazon's streamer, favors its own ecosystem, at least in terms of hardware.
