IoT researcher here. You can buy devices with LTE or GSM connectivity, or Bluetooth LE if you prefer. Those still work well for battery devices since the new Bluetooth provides sleep cycle syncing. Also for LTE sleep patter synchronization is being added.

I know that part, and battery life is not the issue. My issue is more with the Electric Imp specifically having everything communicate up with the mothership. For background, the application I wanted to use it for is a costuming project with lighting and sound synchronization, where having to send my data up into the ether and then back down into the other costumes and props, in areas with potentially no GSM/LTE signal, is a no-go. There are quite a few bits of TCP/IP that would make my job easier, but dependency on an outside server isn't one of them.

I came to say the same; my application differs but the breakthrough is not SaaS, it's Moore's law even while Dennard scaling is running out.

I specifically mean the density at minimum cost per transistor. ARM cores are now providing what I used to need x86 cores for.

Embedded has been around longer than any other app.
