I don't really need it, but even if it's true that the Switch tablet has a touchscreen for convenience, you'd still need proper emulators. DraStic yet hasn't been RE'd to the point that anyone could port it to any other ARM device, if I'm not mistaken. For 3DS it might take some kind of "3DraStic" emulator instead of Citra to get satisfying results. I'd actually like to see that in the future, since it opens up 3DS games for smartphones as well.
