The Nokia N770-N9 saga was too good to be forgotten. IMHO, Librem should include some form of physical keyboard to take full advantage of Linux. GNOME is already quite touch friendly, but still.
Aside, Jolla seems to be going to be purchased quite soon. I hope the new owners try to come up with a new business model that involves open-source. Sailfish failed to attract a critical mass of developers due to closed components and never meeting their own open-sourcing promises.
Be aware, making software open source involves a lot of work. You don't just throw stuff over the fence and be done with it. You need to maintain it, review and apply patches, answer questions, write docs. That doesn't come free, and doesn't help the cause of surviving in the short term.
Just look around at all the businesses that have failed to make a sustainable business out of mobile linux phones. Ubuntu Touch is dead, and forked into UBports. Firefox OS is dead, and forked into something else. Purism has a good marketing team, but they are just starting. It is not easy to create a sustainable business out of this. And users are very critical and often demand feature parity with iOS and Android.
I don't understand this. None of that is necessary at all in order to release the source code. Just make it available to download. Heck, you can even "protect" it (nominally) with a download code that you ship along with the device, like you find with music.
I don't know anything about their team and their experience, but that Jan-2019 release date could shift quite a bit. Especially if they need custom tooling or non standard parts. 6 months will evaporate really really fast, when retooling or changes in material is involved.
I love the project though and I hope they succeed. I have been looking for something like this and I will surely buy one, if they can deliver.
My last Samsung phone ended up being more than twice as thick anyway due to needing a Mophie external battery case just to make it through a full day of ordinary use. My ideal is a phone with a huge battery and sturdy enough not to need a protective case, if that makes it 16mm+ thick I'm absolutely fine with that.
