The Asus PadFone Mini, of course. A 4-inch smartphone that transforms, well not really, into a 7-inch tablet. We've all seen this before, the father of the PadFone line is the Asus PadFone, announced back in 2011. We are basically just seeing upgrades and a PadFone that is smaller than the original PadFone's 10-incher tablet dock. The smartphone on this duo looks like a ZenFone 4 and probably it is a ZenFone 4 but anyway, once you put this smartphone on it's tablet dock's behind, you literally change your mobile device experience from a small 4-incher to a bigger tablet which now offers a 7-inch display real estate.
