The pinephone is very exciting in deed! I can't wait to actually try it out, its cheep enough for most people that they can grab one without worrying to much about their bottom line, as well which is great!
The OP3 port is looking amazing, cant wait to see it in the official installer, for anyone with a OP3 to easily install.
I think the OP5 is gonna be worked on after that, but I'm not sure since it's Vince's main device atm, and I believe that Treble is still an issue.
I'm a big fan of the OnePlus devices personally, and the more OnePlus devices with an ubuntu port, the better, I hope that Halium gets support for newer versions of android, so we can get a convergence OnePlus device with MHL out, but thats a distant future it seems.
