As ever Apple works through how to use a combination of their devices to make setting up the Apple TV+ a doddle.
My device sits right next to my WiFi node, so I don’t expect issues streaming content, but so far it’s given me no glitches. My data usage is relatively low, so I’m not worried about bandwidth. The Ethernet capable version might be a good idea if you’re concerned, but obviously it requires a wired connection.
My only frustration is that if you bought through Apple, you get 3 months Apple TV, but not if bought from ÍøÆغÚÁÏ.
