IoT is just the latest marketing buzz phrase. Just like "Big Data", it's something that the group of folks in the industry that don't actual do technical work can throw around to generate buzz. IoT has no real standards and still doesn't address security issues. It's a hodgepodge of crap being generated by wonks that just discovered embedded programming by playing with an Raspberry PI and made an LED blink. It's attempt to bootstrap additional revenue off the "Maker" movement.

That being said, there's a lot of cool hardware and software for hard core geeks to play with. We will see more real products come out of the technical advances, but 64 bit toasters with GPS, DSPs and FPGAs is just hubris. Hopefully the security issues don't get worse, but I doubt it.
