Nintendo isn't immune to this in their handhelds.
First gen GBA didn't have a backlit screen.
First gen Fat DS - nuff said
First gen 3DS was pretty good, but the better 3D tracking, analog nub, bigger screen, and more buttons of the New3DS made the original obsolete even when not factoring in the increased power.
If the Switch gets an upgrade I think the first gen version we've been enjoying will look pretty shabby in hindsight, much as I love the thing now.
