While I fully understand and support the underlying idea, I can't stop thinking that the biggest advantage to the Uno and the RPI aren't their hardware efficiency. It's more their ecosystem efficiency. So the form factor is very very important. Maybe even more as everything else. The usual way is to make something better yet compatible, then leverage your own ecosystem to try a different form factor, which can fail without taking down your whole product line. In the very same way as the infamous xkcd https://xkcd.com/927/ https://xkcd.com/927/
