To be fair, the Switch changed the storage medium and Wii and Wii U disks are bigger than the console itself. That is not to say that Nintendo has not had multiple storage mediums compatible with the same consoles, for example: Gamecube miniDVDs and Wii DVDs working with the Wii and Gameboy cartridges and Gameboy Advance Cartridges working with the Gameboy Advance. But I think I am willing to cut Nintendo some slack for the Switch given the many compromises they must have made to fit that much power into a hand-held unit.

I am sour however that the Wii Remotes are not working with the Switch though, as I find the Wii Wheel to be a superior experience when playing Mario Kart. There is no technical reason for this as far as I can tell as the Switch still uses Bluetooth for connectivity. Now, there are new wheels, but just like the Joy-Cons, they are far too small to be comfortable given the size of my hands.
