That chart seems silly to me. It shows a classic response when someone asks a question that doesn't make a lot of sense. A nice bell curve.
Everyone should be familiar with M2M and IoT, because it's been all around them for at least 20 years. And I mean "at least," because anyone associated with computers in any way, or the military, or factory automation, has seen M2M and "clouds" for a lot longer than that!
Rick, on slide 3, at the bottom of the second figure, there is a typo: "Securoty is the top issue."
I have to agree with @Bert22306's comment below -the question needs to be precise enough to get useful data that has some basis for interpretation and conclusion. Otherwise, Mark Twain's famous comment on Statistics applies!
