The good news is that the best Nintendo platform is also the best mobile platform: The Steam Deck. It plays Nintendo games better than Nintendo consoles do, and as a bonus, it plays everything else.
Have you ever tried to dock a Steam deck to a TV? Have you ever tried to use physical media with a Steam deck? Have you ever tried to get 5 hours of battery life with a Steam deck? Have you ever put a Steam deck in your pocket? (I do have big pockets, but at least with the Switch Lite, it's possible.) Nintendo will be just fine. I personally will never use a platform that can kick me out on a whim, or could screw me…
Dude, you have to rebuy all the games you've already bought and already own every odd generation. Imagine paying for NES and SNES games, Wii and Wii U games and other old garbage you already own? That's Nintendo.
On steam you have absolutely massive library dating back almost 20 years by this point, and it comes with you every time you buy a new device, whatever it might be a PC, laptop or SteamDeck.
Yes, steamdeck is pretty large and bulky, but you can get 5 hours battery life on non-demanding indie titles (ie. Hades on the updated deck OLED models)
Yes, you can dock a Steamdeck to a TV easily.
It's all around better, completely open device, minus the size (and battery life in demanding AAA titles switch can't dream of running anyway)
