Agreed, it would have been better to have the chief scientist discuss the core technologies, design and potential applications than watch an Elon Musk/Tony Stark ripoff drive his Tesla-S home to his sweet pad and knob around with a CAD model of a rocket via a seemingly non-intuitive interface. If the device was only a few hundred dollars to purchase then the marketing video might have had some merit. But at 3k, you're selling to people who want to know how it really performs, and what technical trickery Mann might have introduced to make it an exciting human-machine interface.
