>A 2-3 generation old pixel on the second hand marker is not expensive at all though.
Sure but at around 300 bucks is still way over 50 bucks.
And even if you get a used Pixel 8, having separate phone and computer adds a priceless layer of redundancy and flexibility.
If someone steals my phone, I don't want to also loose my work PC with it.
"work pc" -- random 50 dollar fire hazard running Linux. Anyway, those Android phones though they are obviously going to be the unreliable part in this story.
You are also buying a soon to be unmaintained device which will fall out of security support.
That $50 PC can run linux with the latest kernel for the next 20 years (maybe longer).
