I bring a Nintendo Switch with me when I travel because it helps cut down the boredom on flights, especially international. Books are great, movies are great, but sometimes I just wanna play some indie game on a halfway decent screen with real thumbsticks.

Could I do that with my laptop? Maybe, but I'd rather carry just my work laptop (heavy XPS 15, has everything on it, but can't/shouldn't install games) or a personal ultraportable that might not be powerful enough
