Nvidia's embedded boards are EXPENSIVE. So expensive it limits the applications dramatically. They also require a different skillset in people to set up which drives up the cost.
We did an analysis for a security project that required visual inference. It turned out all the extra costs to setup with TX boards meant it actually made more sense to have mini desktops with consumer gtx cards.
I am excited to see the performance of the inference module. If it's decent at a good price, that opens up so many pi/beagle/arduino applications that were limited by both cost and form factor of existing options.
