I just don't get what the purpose is though. You've lost access to the proprietary primary library, which was the original reason to buy a Switch. If you want an emulation console there are cheaper alternatives as well other than the Deck, I was just using it as the de facto standard handheld.
There's no benefit to nuking the OS and replacing it on a Switch. At least with something like a ROG Ally, you can make the argument that flipping over to Linux would make the handheld more performant and energy efficient. That cannot be said about flashing Lineage onto a Switch which functionally makes the system considerably less useful.
The Switch OS is already optimized and designed for the hardware. It's as good as you're going to get, and it's also already Linux. I would much rather suggest cracking it to put custom firmware on the device based on the Switch OS; you would get more use out of the device because it could still play the games and be rigged to emulate the older ones.
It's cool Lineage did this or whatever but it's kind of a pointless and weird flex.
Correct, however rooting and installing lineageos for...? It will probably not let you play Nintendo games from their cloud. Might be cool as a emulator gamepad, but there's plenty of great options out there for less now.
It makes a really really good android tablet in my experience and breaks in half every other android tablet I have used as of recently and I can't get rid of it.
Like sure battery life isn't the best. But the amount of things that you can do with a generic android device is astounding and is well worth the investment and it has more ram than any other tablet in its price category when bought used on eBay. Such that it actually functions really well compared to the shittastic tablets you'd be buying for its price point.
That and you can just run Linux on the Nintendo Switch anyway and have a fully functional computer that mogs any single board computer out there including the raspberry pi. Like having better hardware decoding and actual vulkan and opengl support that isn't gimped due to laziness surrounding drivers that surrounds these computers.
I sold my switch that I stupidly bought when they first came out. People are still buying them and I got more than I expected. Switches with lower firmware numbers are probably worth more money due to jailbreaks and stuff but I didn't research switch mods or anything.
