In the Android world, there's a constant (borderline tiresome) game of one-upmanship. But the HTC One X, offered through AT&T for $199, has all the makings of a flagship phone with serious staying power. It all starts with a stunningly big and bright 4.7-inch HD screen. And inside this beast resides a 1.5-GHz Qualcomm Snapdragon S4 processor, the fastest camera we've ever used and Beats audio for enhanced sound. HTC has also redesigned its Sense software, promising a lighter touch on top of Android 4.0. So is the One X the one for you?
