I just got my Z3 last night from T-Mobile, I am coming over from a Nexus 5. The screen is gorgeous although I think screen resolution and specs are over rated on smart phones, everything looks really good. The design of the phone is "sexy" if you feel comfortable using that word to describe a phone. It looks great. I do not like the glass back, it looks good but is super prone to fingerprints and is very slippery. I got a Rinke fusion case which fits nice and is slim however that attracts fingerprints on the back as well. I'll be looking for other cases. Phone works great so far, I didn't like the Sony interface so I downloaded and installed Google Now launcher and it feels just like my n5. It's fast and snappy. I haven't had time to really test out the battery life or the camera yet, I took a few pictures and was not really impressed however I have to play with it more. I do LOVE the physical camera button. It's such a simple and great feature to have, more phones should have it. The tap to wake is a nice feature but doesn't work all the time. So far so good, I haven't been able to put it down yet.
