Or if you don't want to fuck around with random refurbished shit and want a consistent, stable platform.
What does that have to do with raspi, where every other version they fuck up something basic like USB or power and then clearly don't do any testing before releasing it on the user base?
You won't get a refurbed PC for that, you'll get an ebay special you'll need to refurb yourself.
Refurb? What are you talking about? You can buy a used dual-core NUC with 4GB/16GB for $50 any day of the week, and when it shows up you plug it in and load software on it and you're done. You don't have to play any stupid games with bootloaders, you don't have to run special snowflake arm versions of anything, you just install and go.
It's also kind of daft to compare a refurbished NUC to a new Pi.
What's daft is your marriage to this straw man bullshit about refurbishing. I have no idea what hole you pulled that out of to try to make your argument valid, but it's literally insane and I'd like you to stop trying to gaslight me.
