I feel this kind of service is extraordinarily important. As a software person who's gotten into hardware and robotics I am continually frustrated by the tyranny of choice in electronics. There are so many ways to accomplish a goal and it's so expensive to do things wrong that a huge amount of my time is spent researching parts rather than building things out of those parts.

The more companies like this develop a clean pallet of available parts (even if the excuse is price control) the better! While I'm sure many people will be quick to point out that solid EE is hard for good reasons, I think we're light-years from the point where we can say "we can't make useful prototyping any easier."

Perhaps this exists and I haven't found it, but I'd love not to have to even think about parts and assembly. I want to write a clean high-level spec for the functions of a board and have part choice, fab, and assembly taken care of for me. I see services like this and ciruits.io as great stepping stones on the way to that goal.
