That's a lot of things that can break, get lost, etc.
Also those tiny controllers would probably cramp my hands after like half an hour of use.
Also also, a lot of what seemed like automatic functions are probably not all they are cracked up to be... (e.g., the Switch won't turn off your TV when you go from console mode to handheld mode. Someone was doing that off-camera for the trailer.)
I'm pretty underwhelmed.
