"Backordered" is something of an understatement. I placed my order in February 2018 and still haven't received it.
I think the reason system76 has less issues is that it isn’t custom silicon. I’m not sure about Pine but perhaps it’s the same case?
The Librem 15 is a decent laptop and is very serviceable / easy to repair but for the price it’s definitely not as good as the build quality of a Dell XPS for example.
I really like the idea of a quality open source phone (hardware and software) that isn’t sold by surveillance capitalists, which is why I support them but I still don’t know if I’ll use it as a daily driver.
