I agree. She's really great for hobbyists and for prototyping. She's done a ton to help beginners. And Adafruit is a very interesting company. I seriously admire her. But as to the original claim that she's "one of the industries greatest hardware designers", when you look at the electronics industry on a whole (an industry where people design incredibly complex things that are used by millions/billions of people), her _designs_ are nothing special.
