I can see a chicken-egg problem here. Without enough users (probably millions), this device is useless. If the device is useless now, it makes no sense to purchase it. The pricing doesn&#x27;t help either: $249! (and $399 after pre-sale).<p>Assuming 10 million a good number to kickstart this thing and make it useful in many locations, they&#x27;ll need to make a few <i>billion</i> dollars sales in the next couple years.
