First order of business after setup will be to download apps and try out that new remote with siri. I believe the 3rd party apps are the primary feature of the new appletv that will move this platform forward and we are only seeing a taste of what is to come. I'm ready...long overdue for the refresh.
I'll be looking to use Airplay connection with Amazon Prime Video.
Since I can't expect the Amazon Prime Video app to appear anywhere on the old or new Apple TV
Good Luck
