One thing that I don't see mentioned here is that there should be a good chance that this thing will not come out of the gate with call quality issues or any performance issues in relation to data speeds (whether the original has them or not). This almost makes it look like the Titan was released as an experiment prior to the opportunity for the release of an LTE phone. The launch in general didn't seem to go well, as if everything was rushed. Perhaps HTC just didn't want to be out of the holiday shopping season and so they dumbed this phone down to release it sooner.
Now I'm not saying that the Titan is a bad phone, or that it didn't deserve a release; I love my Titan. However, I do wish that I had waited to upgrade now, as AT&T's statements have led me to believe that I will be able to enjoy LTE here by the end of the year. That's my fault though, and if I bought an LTE Windows Phone off contract once the service arrived here, it wouldn't be the first Windows Phone I voluntarily purchased off contract...
