Linux on a phone (true Linux) is like my holy grail device. If it's able to seamlessly transition between a "desktop" mode when docked and a "phone" mode when not, even better. I have a Gemini PDA on order (dual boots Android and Linux) which is close but not quite there. Maybe 2019 will be the year of the Linux phone.
Yeah I sometimes really wonder where Ubuntu would have gotten if they'd held on for another year. And If they would have produced a simple but nice dock... But I guess you and me are part of a very small group. I feel I have that more often, I also loved my Pebble Time Steel and I'm still waiting for a good quality ARM notebook (with Dell XPS build quality but much cheaper) which could run Linux.
The problem with the ubuntu phone is that they built a special phone UI. None of the GUI desktop software ran and neither did software from any other OS. On top of that the battery life was awful.
Yeah, I think it's one of the more interesting "Linux on a phone" projects out there. The hardware differences between phone generations aren't as pronounced anymore. An OS that let's you run a device with updates for 5-10 years is a great idea.
