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.
