I did some micropython for a video series I made [1], and I have to say, it took me right back to the days of owning a ZX Spectrum - accecssing a REPL directly over a USB serial connection was very much like these machines, although I know it's not something that everyone thinks is a good idea...
I like the idea that the main interface to the device is to program it in some way or another, and I'm sure that was what led my generation to be as computer-literate as they are.
I'm going to order a Pico today!
