There are a few devices where there are good arguments for connectivity. An HVAC thermostat, for one, benefits as it's the most expensive consumer of electricity, so a smarter device (or access to external resources) makes sense. Additionally, the ability to control it remotely has a great benefit for "oh hey, I forgot to turn off the A/C before we left on our month-long trip." It could pay for itself right there. I really think IoT ought to be much more focused on a few high-value devices. Mostly, I think this is important because they have high value for end users but, as such, are also potentially targets for attacks, and by focusing on fewer devices they can hopefully be made much more secure.
