The time it took you to write this would have been better spent reading the article:
Because Android isn’t technically “installed” on the Switch, but rather an external microSD card, you can switch between the default system and Lineage at any time.
Running Lineage is a big deal for those of us who have a switch laying around that no longer have a use for it.
- It can be an android tv device replacement
- Buy a $20 goose neck tablet mount, and now it’s a way to play streamed steam games or use the android tv jellyfin client to watch/play stuff without using the main TV
- Bedside clock/radio with loads of extra features
- Dedicated HomeAssistant remote
Or, the basic use case - Play emulated games on a neat handheld package with a decent screen on a plane or something, without needing to carry or buy another device.
Have you checked out the bigscreen headset? It’s only doing upscaling to overcome the resolution limitations of displayport 1.4, and the form factor might be to your liking.
Shame about the lens glare effect, but otherwise, pretty cool!
