TCL's foldable prototype: running before you can walk?

TCL's prototype design doesn't have a name, a price or a target window for production. It doesn't even have a working screen. All that will come. For now, I'm mesmerized as I work the hinges with my hands, and imagine what it'd be like to use a triply folding device.

Folding one panel under, for example, could turn a portion of the screen into a digital keyboard while you use another part as the display. When you fully close the phone, you'd be able to use it as a really chunky handset... More here.

It could take some time to move people from simply pulling their phone out of their pocket and doing things instantly.
