Today 10 years ago I went to Poland to buy a Phone with pre installed #Firefox OS on. The Phone was a Alcatel One, so very shitty. Two years later I installed Firefox OS on my Nexus 5 instead.
It was a very good concept, but sadly rolled out on too shitty hardware so it never caught on.
today there are comparable projects with like postmarketos and ubuntu touch for specific phones, among other linux mobile projects
Also Sailfish OS (though it's not fully open source), which I use.
I sincerely hoped Jolla would at least continue to make one technology demonstrator hardware model available for purchase by enthusiasts. The current situation where I have to buy a phone and then buy OS separately is not feasible for me.
I mean, the license cost me $50 (maybe €50, not sure). It's not that much, just pretend the phone cost $50/€50 more.
Jolla can also be purchased and used in very few countries. 4 according to their list. I don't mind paying for an OS and a phone, but their phone support is also only for very expensive Sony Xperia phones. So I can see why it is not feasible for a lot of people
If you mean the OS, it can be purchased in all of European Union plus some other countries. With VPN you can purchase it everywhere. Though I read that the Xperia phones don't have the necessary bands for USA.
Ubuntu Touch has been pretty decent, and because of how it's built, device support is a lot more widespread. Although it's in this perpetually broken state now, because of the transition to the Focal base.
No luck at all with Postmarket though, on any of my devices. One is marked as bootable but unusable, but I can't even install it fully
Ahh, my appraisal might be the opposite, PMOS seemed to have better software and support for things like the Pinephone and I thought it ran on more devices, but I am happy to see both projects and it's nice to see both designs
On a device that supports PM, it will without a doubt have better software support. Current UbPorts runs on Ubuntu 16.04 base, so it basically can't run anything new until they fully migrate to at least 20.04
