Not believable numbers
Some (most) of these data points [Internet-enabled "things"] are not believable. e.g., 29% of thermostats aren't even programmable, let alone the small fraction of those that are communicating. What's the source of this data? What are the exact definition of the categories? For example, do headsets count as internet-enabled if they just have Bluetooth?
Finally, are these statistics on the entire installed base (not believable) or just new offerings? And if new, is it just by unique catalog line-item for sale or actually volume weighted by the number of units sold, as well?
