Been using this on my Macbook Pro M1 to play Breath of the Wild and Mario Kart using XBox controllers. My kids and I love it.
* Playing (Nintendo) games with the entire family (4 people, all holding a small controller): every Nintendo game is very thoughtfully designed to get 4 people through the "flow" before the game starts (pick your character, set the options etc.)
* Playing games in the portable/detached mode, it is a joy to hold and unlike a tablet you have physical controls. Most games are so much better than your average iPad game (or better said, the "match three" or mindless clicker games do not rise to the surface as easily as on iPad).
