This type of innovation is only possible with the initial revenue earned from early investors and pre orders. A lot of the manufacturing bills will have been paid off the back of the pre order revenue. Everyone pre booking will have known this and been prepared - as has been proven by comments from guys who have pre ordered.
The guys being sour won't ever order one of these anyway. -They go with the flow, worried about taking risks, while hoping the innovators fail. When it succeeds they'll change their tune. Only dead fish go with the flow!
Without the chancers and real innovative enthusiastic guys creating and backing this stuff there would be no development, no improvement, and no gains. It would just be grumpy moaners talking the talk without walking the walk.
