Been doing a lot of research and I like both phones. My contract with AT&T is about up and I'm not thrilled with AT&T but it's not to bad in central Florida. My big question is just how big a difference is there with the Skin on the two of them? I've held the X in my hand but not the Captivate yet. Is there a big difference between the two software wise? Anything software wise that one can do that the other can't?
