ASUS is finally getting some love from U.S. carriers with its new PadFone X. The combination smartphone and tablet is the first major release from ASUS to land on one of the Big Four carriers, namely AT&T. The device marries a 5-inch smartphone with a 9-inch slate, both of which feature full-HD displays. The PadFone X's Qualcomm brains sit in its smartphone portion, and when connected to the tablet, automatically hands over control to the big screen. Little else is known about the PadFone X in terms of specs and release date, but you can color us very intrigued.
