Question about Apple TV 4k 64gb

Only if you want to download a lot of games. You don't need 64gb for TV/movies - the videos are streamed anyway.

i bought it and the 32gb version will do.

Hello the version with 32 gb is completely sufficient
I am completely satisfied with it

if you buy a lot of films then yes, otherwise no, but of course you can because the surcharge is very small....

no

I would go for the 64gb version as it only has a small premium.
