So an additional device hanging in the breeze just to gain even some features and pico is hardly a replacement for full rpi gpio. Doesn't really seem like a better solution.
It all depends on what your usecase is. If someone's just starting out and wanting to do gpio stuff with a Linux os, yeah the pi may still be the best bet since it's got such a large following and guides written. But if someone's got more experience and just needs a cheap small form factor machine to run Linux and interact with some non mission critical gpios, a small nuc with a pico will give you a greater bang for the buck!
