I will let you know when I get mine. What I can tell you is that the same camera is in the four new Motorola phones. I think the people giving the bad reviews of the Ultra are just too picky.
I think that this might be helpful for you (in this video they use the Ultra, but remember the camera remains the same).
Also, keep in mind that photography is 10% the camera, 30% lighting, 30% having the right distance and focus, 20% placing your subject in the proper frame, 10% personal preference.
Compared to today's cameras, people would say that Ansel Adams' camera was crap. Yet he was a master photographer and his photographs are still legendary. A good photographer can get a great shot regardless of the camera. To me having quick access to the camera is the most important.
