Honestly I'd go for if it was a solid mod in an OLED, my V1 is great but hot damn I want that OLED but can't give up my CFW lifestyle.
I've played around with Ubuntu and LineageOS for many many hours and it's just not worth it, especially now that we're getting an official N64 app, and have access to a Saturn emulator in Horizon now. That basically covers all your emulation bases except for GC which could be run on Ubuntu/Android but you really don't want to, the performance and cracking audio is a no go for me. If there was a way to get a stable 30 fps in WW, Twilight princess, Double dash, then maybe, but from what I've tried there is no way.
Lakka is pointless now.
I honestly don’t know what your on about.
Android N64 will outclass the N64 switch online easily, that you can get flawless performance with HD texture packs says enough, & without, you can still upscale to 400% internal resolution. Even If by some miracle nintendo allow 16:9 full screen & upscaling, texture packs are 100% going to be a no.
I also doubt Gamecube emulation is coming to the switch anytime soon, which also works pretty solidly on android. You say its not worth it, but about 70-80% gc games run fullspeed with OC, & ya their is no cracking audio in those games….
Someone would need to create a program aswell to run other games other than the default 9 games nintendo offers

.
You say android and ubuntu arent worth it, however for every bit of emulation except 3ds, they literally crap on HOS. Which makes me question how long youve actually spent on ubuntu/android, or weather youve tried the right apps or optimisation.
If your going to blow that much money on a 4 year old hardware console, you can get a steamdeck for cheaper…. Which offers over 4X the cpu speed & more storage.
Buying an OLED for hardware hacking is literally binning cash imo.
Even if you play 100% portable, id still not consider it a good investment.
