Your first few days with the phone will be laden with pop-ups telling you about new ways to do simple things. The camera has a bajillion modes, settings, and options, far more than you'd need, and, frankly, more than the quality of the camera in this phone actually warrants. There are a million ways to share things, from DLNA to AllShare to AllShare SugarSync to ShareShot. You'll need a tutorial on each. There are a dozen new gestures, some good, some bad, but all will be bombarding you with newness. New things you have to learn.
