This appears to be the AT&T LTE variant of the One X (Snapdragon S4).
It's the same price as the 16GB Nexus 4.
Advantages over the Nexus 4:
-LTE (compatible with AT&T and T-mobile)
-Better camera
-Better screen
-Not a glass back (i.e. a lot less fragile)
Disadvantages over the Nexus 4:
-Worse CPU and less RAM (dual-core S4 and 1GB RAM, as opposed to quad-core S4 and 2GB RAM on the Nexus)
-Sense 4 and Android 4.1 (and slow updates compared to the Nexus)
-No HSPA+ on 1700/2100MHz (bad for T-mobile customers in non-refarmed areas)
