I remember the “Draft-N” era. All those Draft-N devices on the shelves, but they all had compatibility issues of varying degrees, because it was Draft-N and therefore unfinished, but people wanted them because it was the new hot thing, and the final N spec kept getting delayed because they had to keep changing it to accommodate the Draft-N devices… It was a horribly vicious cycle.

Explaining all this to customers who knew nothing about spec development was possibly the worst part.
