Becoming possible to have an accurate diagnostic machine in your home or hand that could give you advanced warning and preventative measures to take. Could eliminate any diagnosis problems when it comes to patients forgetting or being reluctant to talk about symptoms with there doctor. A patient that may not discuss a symptom or forgets to would be less reluctant if dealing with a device. ? 

My primary concern with this tech is the level of privacy/hacking with the device its self. If it's communicating with a doctors office or the CDC regarding symptoms .... not sure about that.
Awesome!  Using video to monitor a newborns pulse with a video camera (starting a 1:25min).   The other uses are just as cool.
