Asus' original PadFone took an Odyssean twelve months to find its way from announcement (and re-announcement) to a retail release, so it's no surprise to see its successor making a debut so soon after the first units hit store shelves. The PadFone 2 maintains the Android smartphone trend toward bigger and better screens, by stepping up to a 4.7-inch 720p IPS display, and also bumps up the megapixel count on the camera, moving to a 13MP shooter. The backside-illuminated sensor is provided by Sony, making it likely the same one as seen on the Xperia T. The PadFone's processor has also been beefed up in a major way, as there's now a 1.5GHz quad-core Snapdragon S4 with 2GB of RAM at the heart of the new device.
