Hope I'm in the correct category!
Been thinking about using a Jetson Nano (the $59 one) instead of an RPi, now that there is a $59 version, similar price to the $55 RPi4. Has a port been accomplished? Has anyone tried? Is anyone even interested? 
The Nano is quite a bit faster than even the RPi 4, and Ubuntu software on it is optimized for a large number of AI tools.
So, anyone for the Jetsons?
