I've recently heard a lot about the Internet of Things, and while so far I've mainly dismissed it as a gimmick that may become important in the future, I've been wondering if there are some applications that are already interesting, useful or simply cool enough to check out. There've been some technological advances in the past that I simply wasn't aware of until they'd become established, so I was wondering: have people here already been exposed to the Internet of Things? What sort of tech and applications have you interacted with? Which of these do you think are already at a point where they're of interest to others than just technophile early adopters?
Edit: It's quite possible that a number of things I've already got in my daily life would count as IoT, but I'm simply not aware of all the things included in the term.
