And who would pay for what data of the toothbrush? Merchants to place personalized ads? Life and health insurances to adjust their rates they 'need' to charge?  Should the toothbrush order a new one? Maybe i will leave the old  toothbrush online to collect  IOTAs for the actual state until i can buy a new toothbrush from the collected  iotas?

While i have no doubt that IoT will be a huge market i would be much happier it the examples from the lot of  use cases would be better.
