The Asus PadFone Mini is a high-concept, two-in-one cell phone and tech pad. Launched at the Consumer Electronics Show 2014 in Las Vegas, this innovative device allows you to get a pad and a phone at the same time. When you are on your phone and you feel the need for a bigger screen, just slot the cell into the back of the pad to turn it on. You'll then see what was on the first device your were using.

The Asus PadFone Mini has a 4-inch screen for the phone and a 7 inch 1280 by 800 resolution screen for the pad. Both run on 4.6 gigahertz Intel Atom. You don't have to worry about your phone going out from running the pad, as they both can be charged. Additionally, for all you selfie lovers, the camera has 8 mega pixels and instead of pressing a button to take a selfie, the photo will automatically be captured when a face is recognized.
