I have an idea for Apple. Create a software download center in TV OS so that in a household with multiple devices, one software copy for each device type could be downloaded and stored on the Apple TV storage and then devices on the LAN could download those software updates from the Apple TV.
I have four Macs, two Apple watches, three iPads, three iPhones, and two Apple TV’s. I would love a feature where I could specify all the devices I own in the Apple TV interface and have the Apple TV automatically download the updates when they come out. Then, I would choose when each device would get their updates from the storage on the Apple TV.
A 64 GB Apple TV could store a software update for every device in the household and help not to exceed data cap. Also, for those with slower download speeds, this would be a huge improvement. The Apple TV can be downloading software upgrade for all home devices overnight and then the users can quickly download updates over the LAN.
