OP no need for the expensive Apple TV as at the moment the apps haven’t been developed, just get the basic one. If you have an iPhone/iPad you can use that to drive content (eg iPlayer) in addition to resident apps. The phone/app provides the extra functionality.
If you want to look at something else and don’t mind fiddling around a bit a Kodi box might be interesting (Google m8s). You can load the Kodi software onto your Mac and have a play. See this thread for a general discussion Linky
I’ve always eaten bananas rather than apples. As it was cheaper I thought I’d buy a pear but I couldn’t work out how to eat it and it went mouldy. If this is typical of apples I’ll stick to bananas from now on thank you.
