Derek Zoolander would be all about this teeny tiny backup phone.
The Light Phone is still in Kickstarterland, so, you know, it may never exist. But if it does, it will fit right in your wallet, with roughly the XY dimensions of a credit card and a thickness of just four millimeters (or 0.16 inches). It’s a standalone phone with its own SIM card, and you can forward calls that go to your normal number straight to the Light model—then leave the pocket computer at home when you want to travel light.
Interested? You’ll have to wait until June 2016, if full funding happens.
