I think that works out tremendously well for Nintendo, especially when you look at the Wii-U vs the Switch.

I shot a video at CNET in probably 2011 which was a single touchscreen display (i think it was the APX 2500 prototype iirc?) and it has the precise dimensions to the switch 1.

Nintendo was reluctantly a hardware company... they're a game company who can make hardware, but they know they're best when they own the stack.
