I had a remarkable 2 for a year and was very dissatisfied with how hard it was to modify or run custom scripts or third party gui apps on it. Then came the subscription stuff and I ditched it.
Bought pinenote and even though I'm no linux developer, I've set it up and it works very well. Been using it for 3+ years now.
The build feels cheaper compared to remarkable, but the hardware spec is much better. And the best part is I can just run syncthing or kdeconnect or any linux desktop app on it and it's great.
