Console/PC: Loads of storage space, dedicated controllers, and big screens.
Mobile: Barely and storage, fake touchscreen controllers that take up screen space, screens smaller than a 3DS.

NGL you legit had me worried this was a real announcement I somehow missed. Only other announcement I can see causing more of an uproar is if Nintendo brought back F-Zero as a F2P mobile game where you have to gacha everyone besides Captain Falcon (though given how Nintendo's done their mobile games I think they'd be smart enough to know they need to announce a proper mainline entry as well, like how people didn't really get pissed over stuff like Animal Crossing: Pocket Camp or Fire Emblem Heroes since we knew Three Houses and New Horizons were also coming to Switch).
