I'm happy to answer any questions around this! We've been working on this since update since we launched the product last year, so we're excited to be able to share it today.
Why is there so little interest in ARM-based Linux laptops? Does AMD (or Intel) have anything even close in performance / watt that one can get from an ARM-based system?
ARM-based laptops are definitely more niche and if you don't have a large company like Apple forcing the adaption, you'll have a hard time to support proprietary software, including stuff like drivers. It would absolutely be cool to have an open ARM-based high-end laptop, but it's not drop-in like AMD.
