Agree with you there. A lot of this IoT hype is just, hype.
In my case it is more about professional garden and forest equipment
that gets more and more "intelligent". Think of automatic lawn-movers,
they today have GPS satnav and cellular "phone-home" features. Even
"simple" chainsaws today have processors in the carburators that are
individualy programmed and callibrated. All this information has to
be handled in a way so that service and repair shops can access it.
I do not see that all this is techinicaly anything new. And it doesn't
have anything particular to do eith any specicific operating system.
