Things like this is what makes me feel that the mobile market came to a screeching halt somewhere around 2007, and has barely been picking up speed since.
Also, look into the neo900 project and Pyra. Neo900 is trying to upgrade the n900, and Pyra is the successor to Pandora, which is a pocket computer in a semi-similar vein to the old nokias. Neither is finished, but they're worth a look.
The other project was called Moblin. It was an Intel project.
It's a shame the N950 never got a proper release. The N9 got praised highly on release, but the N950 would've been the true successor to the N900.
The neo900 makes me sad, because it's basically my ideal phone, but the price is just too much for me. I know it's not their fault, the low production quantities will do that, but still. It's an updated n900, with a fully FOSS stack and an isolated baseband to boot... awesome.
Plasma Mobile and Tizen are my only hopes for getting a non-Android Open Source OS on my phone.
Reading this made me so sad. This is exactly how I feel. Nothing will ever be good enough again. :(
As mentioned, it'd be a usable device on its own to this day. If newspaper sites hadn't become unusable without an adblocker, if I didn't need browser updates every nanosecond and if the latest memory-hogging web trend language wasn't, well, what it was. I'd still use it.
Now I own two mobile devices. A BlackBerry Passport. Great UI, physical keyboard, indestructible. Dead software ecosystem, horribly closed source, last of its kind and while there's a lot to love It's not hard to see why. Then there's a rooted HTC phone. Great choice of software (termux alone makes up for so much). Hate hate hate ssh'ing with a touchscreen. Typing generally. Terrible battery life. Seems like it'll die from one harsh drop.
If my social life would not force mobile messengers on me, I'd have gone back to 20€ dumbphones and text/voice only. Though I bet even those come with a horrible browser and the accompanying remotely exploitable holes now.
All in all? Wonderful project. I'm very much hoping for a third player in the mobile game.
