I think it is a combination of being the predecessor to such an immeasurably successful initial premium Android device offering from Verizon (the Droid) and also the fact it has the sought after sliding QWERTY keyboard.
I am also at a cross roads... wondering which phone to upgrade to. I REALLY like the 8mp 720p camera/camcorder on the X, but I like the keyboard on the Droid 2. Other than that, they are pretty similar.
I wish I could make up my mind... how much of a difference does 3MP make on a cell phone camera anyway!?
