Constantly amazed at folks who don't appear to have any relevant experience pretending to educate folks who clearly do. You managed to list 4 things before punting to "etc." and 3 of them were lifted from the parent without modification. Can you explain how the only thing you added, marketing, scales per good sold? Why is "fixing defects" a one-time NRE and not related to the volume of product produced? But who can forget the stellar recent hardware companies like Fitbit, Jambox, Sonos, and Pebble all of whom waited a minimum of 5 years before bothering to introduce a second product.
