It is basically like a basic iOS device so the apps are separated and by each developer. You can rearrange the Home Screen and do folders in the same way. The App Store is similar and just has the tv specific apps.

The Apple TV app is exactly the same as the app on other Apple devices, but you don’t have to use it. (You may have to change a setting so the home button goes home and not the tv app but I forget)

The third party apps are pretty much like using Netflix/youtube/whatever on an iPad. So if you hate them they’re you’ll not like this.

If you can try one I’d give it a shot.

Also: some people don’t like the remotes (especially the older one), but I really like it. It’s nice that it charges with usb and I only charge it like one a year.
