I don't see any real killer (technical) feature. But I think that's always been the case for the Raspberry products: you could always get the same (and often better) features in other boards (though this may be less true as of the Pi4 which actually was and still is very competitive in the SBC market). The Raspberry Pi was developed for teaching, as a low cost board that's easy to work with and that has good community support. It wasn't intended to be the most advanced board for your projects, and you could always find something cheaper if you really wanted and didn't mind the hassle.. The Pico is very similar. You get it for less than 5 eur from official distributors in Europe, you plug it in and it shows up as a USB mass storage device onto which you drop your program and off you go. I can see it being a very popular way to get started with microcontrollers, and just like Arduino, that popularity is not a function of features. I'm curious to see where they take it though. It's their first in-house chip afaik, and the board is rather bare. I wouldn't be surprised if they release variants with more features.
