In my opinion it seems the Pi was too good at fast and cheap prototyping and people started shipping products based on it, overlooking the fact that the hobbyist and unreliable nature of the board wouldn't necessarily scale as hoped.

It always looked to me like the Pi was supposed to be used some steps before hardware integration and shipping.

I am glad products are built on it but I was a bit worried when I had to evaluate a Pi based solution for digital signaling last year. Maintenance was a key factor in the proposals.
