Are there any phones that are actually worth upgrading to from the thunderbolt? Let's all be honest, the HTC Thunderbolt rocks. It's very solid and I've come to love this phone and all it can do. I've been looking at the Razr Maxx, Rezound, and Galaxy Nexus, but they all don't seem worthy of an upgrade. The GS-III and the Razr Maxx HD look intriguing as well, but are any of these phones that much more different?
