In addition to the incredible engineering work here the OP casually flexes by showing the development happening _in an economy class airplane seat_.

And the guy next to him is just staring at his phone, probably thinking, "I'm not even gonna ask".

Although if it were me I'd probably annoy the heck out of him asking why he had a Wii on the airplane!

Looks like a Switch 2 actually.
You're totally right, it's a Switch 2.
