Discussed in HN many times, but worth restating once more. The N9 was fantastic. A joy to use, and in many ways the best design, both hardware and software, I've ever handled. Everything had been designed with care and some UI elements remain unmatched.

I think I was one of the first developers that got an N770 engineering sample (the first product in the N770-N9 saga) and it was really clear that they were onto something. Sadly, internal politics won over company and consumer interests. It took them extremely long to let this be a phone, not just an "Internet tablet". It was bizarre.

The same team is now behind Jolla/Sailfish. It's pretty remarkable how far they've got, but it's obviously not a perfect product given how small they are compared to the other mobile juggernauts. However, it's usable as a daily driver and, with a critical developer mass, it could get somewhere. There are already quite a few indie apps.

Crucially, I think it's the only platform that has the potential to set you truly free. GrapheneOS is the other alternative I can also endorse and tolerate, but it has a different set of compromises, and it's a bit fragile to Google pulling the plug. But it's great in its own ways.

To add to that: Elop announced the end of N9 weeks before it's release and more then a year before the first Lumina was available. Dead on arrival not even shipped in major markets. Yet the N9 was years ahead any competition of that time.
