I figured I would make this thread to discuss possible uses for this technology. It is being targeted for release at Christmas, and they seem to be sticking with that deadline.
I have met some IoT entrepreneurs, for example, who have worked on creating wireless IoT toothbrushes. I am thinking that Iota could be perfect for ordering replacements with the simple click of a button. Perhaps the toothbrush could have some charging station, and you can easily order replacement toothpaste, floss, etc. very quickly and efficiently.
I think that there can be some massive profits involved with anyone who sets up a payment gateway to convert Iota on the fly.
Any other ideas?

"Wireless IoT toothbrushes" This is probably the dumbest idea that I've ever heard.
IoT toothbrushes will be able to sense gum disease, cavities and so on via sensors, not to mention analyse your saliva for things like cancer, while also tracking your brushing. There are plenty of IoT use-cases for toothbrushes.
