Asus already planning a PadFone X successor
While there are no details on the specs of the next-gen Asus PadFone X, the device will certainly be comprised of a smartphone and a tablet dock, just like the first (current) model.
At the moment, AT&T is selling the PadFone X (pictured on the left) for $199.99 on contract, or $549.99 off contract. The device runs Android 4.4 KitKat, and includes a 5-inch 1080p smartphone and a 9-inch tablet dock. Other features: 13MP rear camera, quad-core 2.3 GHz Snapdragon 800 processor, 2GB of RAM, and 16GB of internal memory. The smartphone offers a 2,330 mAh battery, while the tablet dock has its own 4,990 mAh battery.
Earlier this week, Asus started selling a non-US version of the PadFone X in Taiwan, calling it PadFone S. This comes with a Snapdragon 801 processor, support for wireless charging, and a splash-proof coating. Perhaps the latest two features will make it to the next-gen PadFone X.
