Congrats.
Curious, why did you upgrade from the ATV4K2? Seems like from another thread you created that there really wasn't much reason for you to get the new one.
Was this with a trade-in deal?
Or, you could have given it to a friend or family member. I often do that with my Apple stuff that I don't feel like selling.
A friend of mine starting buying Apple TVs for his home after letting use one of my old one. He used Roku and FireSticks before, and didn't think an Apple TV would be a much difference experience from the cheaper devices, but he ended up really liking the Apple TVs. A short time later, he switched to iPhone from the Androids.
I gave a new ATV4K1 to my parents to help them cut the cord. They hated it at first (Siri Remote learning curve), but ended up getting used to it, then loving it. All of their other (4 out of 5) had cheap FireSticks, and they slowly replaced them all with Apple TVs.
