yeah, I'm excited to get my hands on some Jetsons too. the 4gb memory on the pi is really a big pro though. when one of these SBCs finally comes with 8GB and GPU acceleration for < 100$ we will see some real progress I think.
It might have GPU acceleration but the RPi already comes with 8GB of RAM for about 80$.
