I'm really excited about a true Linux, non-Android, phone, but how far are we from something that's actually usable? There's Pinephone and Librem 5 on the horizon, but any news about their release comes with a lot of caveats. "Early adopters and developers only, experimental software, use at your own risk," etc. I'll happily buy one once it can reliably be used to make and receive calls and text messages and browse the internet, but how far away is that?
