Of course lightening will make it sell more units, as will decreasing price. But no, I do not worry about your comment:
"Normal folks aren't looking to get "subjected" to their device and "tolerate" using it."
The AVP is not some cheapy fad device like a hula hoop for "Normal folks." It is an expensive piece of high tech, and real buyers will buy, just like more than 100k already have. Try to think in terms of expensive high tech instead of in terms of an iPod for the masses.
Think on the evolution of night vision goggles [NVG] as a good example. They were crazy PITA [cost, weight, batteries, performance] from the gitgo, took many years to evolve, and users still today are ""subjected" to their device and "tolerate" using it." But NVG have been righteous tech from their beginning - - and so is AVP.
NVG development was facilitated by the military just like $4T Apple is facilitating AVP.
