Android phones, apps and tablets

It's really a case of: If the display were external (a watch, a tablet, Google Glass if you must), and anything could be a headset... then why not fundamentally change the shape of a phone and make it a pocketable hub for every other device?

And... once you've followed that logic, what are the problems with phones? Battery life has gone to be up there, signal and connection as well... but if you're freed from the shackles of "battery is constrained to fit behind the display" and "most of the external body must be glass/plastic"... then one could make the core of the phone's true functionality (communications) and put it in a body which contained a more capable battery, and if metal bodied the whole thing could be the antenna.

It could fix battery life and signal, whilst liberating us to choose the sensors, microphones, speakers/headsets, displays that we choose.

I just don't see the point of this stuff being on the phone any more. The assumption that it is, leads to bad technology.

A company, whose name I forget, were doing this ten years ago. The central part of the device was a comms box, with the SIM, cellular radio, Bluetooth etc, then you could buy modules that connected to it via Bluetooth. I can't remember what they were called though.

I'll see if I can dig out their name and what happened to them. It was an interesting, and viable, concept.
