Is it a Pad? Is it a Phone? No, it's a Padfone! The Asus PadFone, which was unveiled at Computex 2011, is an amalgamation of a phone and a tablet. It has a phone unit, which cozily cuddles in the tablet portion. The phone basically powers the tablet. The idea behind it is simple - if the user needs a larger screen he/she will attach it inside the tablet and if there is a need for a smaller device, it will be the phone. Pretty neat?
