Saw an article today saying there was a promotion at AT&T to get it for $149. I definitely agree that the dual-core is better for "real world" use over the Tegra 3.
Unfortunately for AT&T and HTC, I am going to be switching to Verizon when the SGS3 comes out, unless it is just a complete bust, which I really don't see happening. Verizon has a far more widespread LTE network and much better customer service. I think it's funny how AT&T advertises that their LTE network is faster, but fails to mention that there are far fewer LTE users on their network than Verizon. If AT&T had the LTE traffic that Verizon does, there is no way they would have faster speeds. *steps down from soap box*
Edit: Throwing this out there...I bet the SGS3 gets root and full CM9 support in less time from its release date than the One X. Any takers?
