Just found out as well through their newsletter!
The Necunos NC_1 is for sale now right here.

It boosts the following specs:

• Chipset: ARM® Cortex®-A9 NXP i.MX6
• CPU: Quad-core 1.2 GHz Cortex-A9
• Memory: 1GB
• Storage: 8GB
• Battery: 3500 mAh
• GPU: Vivante (Etnaviv with hardware acceleration)
• Display: 5.0"
• Body: Aluminium
• Camera: 5 MP 1.4"

Like Purism, they claim:

• Operating Systems: Multiple community driven operating systems to choose from.
• Closed source firmware with memory access: NO
• Binary blobs: NO
• Locked bootloader: NO

Furthermore, interesting to note is the operating systems that you can choose from when ordering:

• No operating system
• Plasma Mobile on Debian
• Plasma Mobile on postmarketOS
• Maemo Leste
• Nemo Mobile
• LuneOS

I know for a fact that Plasma Mobile is nowhere near finished (would hesitantly call it in alpha state at the time of writing), Maemo Leste still has a way to go and Nemo Mobile... Was that ever finished? LuneOS I'm not sure of, does anyone know? Seeing this list I can only assume Necunos is aiming this phone at developers.

Personally, I think their asking price of €1199 is quite high, especially considering the CPU is "only" a NXP i.MX6. Purisms offer of $600 (less than half) including a NXP i.MX8 and hardware switches to turn various hardware components on/off seems the better deal.

Still though, kudos for them pulling it off so fast and quietly Really curious to read the first reviews when they pop up.
