It's not even a discussion. The KB on the X is by far the best most intuitive KB on the market. The Screen is perfect, the CQ is amazing, the speed, the network you name it. The X beats the Iphone in every category except the design. The Iphone is a better fit in your hand, however the X gives you a bigger field of play. And Verizon or ATT? it's a no brainer. ATT is the worst sounding network in America.
