Well, this is definitely a comprehensive list. Not just good for summing up the process of developing the Peachy, but as an example for anyone who considers developing (or even just making a major improvement for) a product. Nothing is just "a simple matter of implementation". Even with something as seemingly simple as recieving a signal and outputting a laser image.

So it looks like there will be another round of heavily modified hardware beta units before the final production batch can even go through...

I'm not surprised that the Peachy will need more Beta testing iterations. I'm more surprised at myself for thinking it would just be that easy.
