These were nice early in the TensorFlow evolution, for things like Frigate...
But even CPU inference is both faster and more energy efficient with a modern Arm SBC chip, and things like the Hailo chip are way faster for similar price, if you have an M.2 slot.
I haven't seen a good USB port alternative for edge devices though.
The big problem is Google seems to have let the whole thing stagnate since like 2019. They could have some near little 5/10/20 TOPS NPUs for cheap if they had continued developing this hardware ecosystem :(
