Thoughts on IR:
When Laura Dale reported that, according to her sources, all games must be playable without touch, I made an admittedly hyperbolic thread about how Switch MUST have a gyro/IR pointing interface to simulate touch screen controls on a TV. Even though gyro/IR will never replicate a touch interface, a touch game can at least minimally function when docked.
One option is to disallow touch games like Severed on the system completely, which would be a shame because Switch is perfectly capable of running the game as intended in portable mode.
Assuming you allow touch games, the interesting case arises when the user is playing the game and they decide to dock the system. From a usability perspective, I think it's better to provide minimal functionality while warning the player that the game experience may be suboptimal because it was designed with a touch screen in mind. The alternative is to throw up a message on the screen telling the player to undock the Switch because it's only playable in portable mode.
EDIT: As a bonus, you can hypothetically play Wii VC games without breaking out your Wiimotes, but the upside-down joycon doesn't look very ergonomic.
