Asus is coming out with the PadFone 2, which can turn its Android smartphone into a 10-inch tablet with its extra casing. The new smartphone is slightly larger than the original Padfone with a 4.7 inch display. Still, Asus was able to reduce the total weight of the combined device to just 649 grams, some 200 grams lighter than the first PadFone. The PadFone 2 features a 1.5 GHz quad-core processor with a 13 megapixel camera and Android 4.0.
