I'm still using the Orange Pi 3 LTS. It's been two years, I've managed to move to another city, and she's still in service. I use it mainly for testing my amateur projects, nothing more. Linux distributions (Debian, Ubuntu) from Xunlong are just terrible. I don't remember why, but I didn't like them. But Armbian has been running on such a computer for almost two years. Well, I love OPi ^)
