Yeah, one of my bigger complaints especially on the Nano was the GPU only had really limited model support (iirc, mostly tflite but maybe I'm misremembering) and it sounds like the newer ones are more normal. That and what seems from the docs to be better headless support would be major improvements. Going further to mainline distro support would make them interesting to me again.

I was always disappointed by the Nano as it was a pretty capable device, but it seemed like not many people picked it up as a platform for cool things which I always attributed to the software.
