I am really surprised by some aspects of this review. I just gave my Nvidia Shield away and replaced it with an Apple TV 4k, and here are some of my thoughts:
Seriously, the reviewer finds the tacky design of the Shield better than the simple but elegant Apple TV?!! I know beauty is in the eye of the beholder, but this is more like a case of bad taste.
The Shield's remote periodically stops responding to commends, for like half a minute - this is a know issue reported by many. The volume control is also the worst of the three listed here as far as accuracy and response to sliding up and down.
The Shield has the worst selection of apps of the three platforms (it doesn't even have an app for Google's own Photos). Roku has the largest selection, while Apple TV has the best designed apps.
The Shield's apps also crash much more often than those on the other platforms.
Yes, the Shield has games, but it doesn't support gyroscope or accelerometer features. Apple TV does and it's thus more pleasant for casual game play, particularly racing games.
The voice control with the Shield's remote is terrible! Half the time it doesn't detect speech, no matter how loud, and when it does, it often misinterprets commands. Both the Apple TV and the Roku are much better.
