Interesting idea, slow execution. Apparently, the tech is working already but not yet decentralized and most IoT devices aren`t fast enough to process transactions. Their user friendly wallet was just released a few weeks/months ago which I have not tried yet but it seemed complicated enough that the average person would not bother setting it up, hence the -1 star. I really love the use cases though: self driving cars being used as taxis which could get themselves repaired, biometric security layers, machines and robots automatically ordering parts and servicing themselves, etc. The idea of making work more efficient and streamlined pleases me and IOTA has the features/plans to do so.
