Asus PadFone Infinity with 5-inch 1080p Display Now Official
It also has 64GB of built-in storage, 4G LTE connectivity, 13-megapixel rear-facing camera with an f/2.0 5-element lens, 2-megapixel front-facing camera, micro USB port, 802.11n Wi-Fi, Bluetooth 4.0, NFC support, and a 2,400mAh battery with up to 19 hours of 3G talk time. All this plus it comes with Android 4.2 Jelly Bean out of the box.
Slide the PadFone into the Infinity Station (dock) and it becomes a 10.1-inch tablet with more than twice the battery life at up to 40 hours. Asus says you can fully recharge the PadFone three times over with the Infinity Station. The display resolution is also slightly better at 1920x1200, though the front-facing camera is downgraded to 1MP.
Unfortunately the PadFone Infinity isn't bound for the U.S. market. It will, however, travel to Europe in April where it will sell for £799 (around $1,200).
