I currently have a Mytouch3g, its served me pretty well, but I have no real emotional connection to it. Its been screwing up a lot more lately, so it's on its way out. The key board has been especially screwy, and annoying.
What I'm looking for now is this
The Sidekick II was my favorite phone, and I'm taking a gamble on this one being a bit more fun than the myTouch, especially with the camera calls and the keyboard... god I've missed a phsycical keyboard.
