As to "who", some part of the demographic who runs JellyFin/Plex/Etc.
Absolute zero gimmicks and zero excitement.
I personally dont care for gimmicks, but I expect them from Nintendo.
The Switch also has motion control for fine aiming in some games (Zelda, Borderlands 2). Joysticks for gross movement then motion controls for smaller adjustments. Much better scheme than Xbox or PS.
Strategy games might benefit.
Every game card is playable, no matter how out of date the Switch is, without any internet connection.
I'll take that kind of functionality before "surprise and delight." We might get "surprise and delight" this generation though, if in part because the change to a modified Samsung NAND over Macronix might be cheaper at larger capacities if rumors are correct.
By comparison, the Wii U with it's "nice touches" was over 5 GB.
This is mostly accurate, but not entirely afaict. I had to connect my switch to wifi in order to update the OS to play Xenoblade 3 (or Tears of the Kingdom? It's been a while).
