Not as bad as I would've expected. Also, apparently it includes a very simple Python environment? https://education.ti.com/en/product-resources/eguides/eguide...
With a CPU 3x faster than a z80, you gotta wonder how many seconds per python instruction.
For a $10 BoM and maybe a year of R&D I would say that $160 is bad.
