Re: Roll your own?
Yes, that's the one I remember.
As you can see from the cost of the components, you’d be FAR better off going into your local phone store and picking up a normal smartphone
Not sure that stands up. He costed it at $158 which, even allowing for the fact that the article was written in 2014, isn't half bad. Yes, you could get a modern smartphone on contract for a lower upfront cost, but you'd be buying landfill android if you wanted SIM free very much cheaper, though I suppose if you wanted to 3D print a case you would add to the cost. The current Pi3B+ has WiFi and Bluetooth, too, which the original Pi didn't, all for essentially the same cost. If you wanted something simpler there are several Arduino-types that might work out cheaper and could run directly from the battery without needing boost circuitry.
But the idea of a phone-shaped device running Raspbian does appeal :-)
