@cryptoindex I disagree; we have barely scratched the surface of IOT. It's starting but "saying not much need" might as well be the same as saying: no way the internet will be a big thing.
examples where microtransactions will be useful for: automatic purchase of finished groceries in your fridge, automatic transfer of finances when you resale a used durable good in sync with the durable good, taxi or meal-sharing apps where everyone shares the cost, in-app/in-game purchases that are very small in denomination, sale of digital goods without an app store - imagine selling a 3d render you created, paying the tiny amount for the electricity used while charging a phone at the airport etc etc etc...the list is endless.
If IOTA does this right it could be huge...
