Best book I ever read on the Internet of Everything was a science fiction novel that had nothing to do with talking about IOE - it just used a near-future world of IOE as the backdrop for an interesting plot.
"Rainbow's End" by Vernor Vinge, 2006. I highly recommend it as a light sci-fi novel, AND as an introduction to how IOE might impact everyday life.

Disclaimer: I work for Cisco Systems, but have nothing to do with the sci-fi novel or Mr. Vinge. Just liked the book.
