I have wanted to feel the nexus experience for years, but never got around to it. Mostly the camera performance was the main problem for me. But this year, I don't have to worry about a bad camera (or even a worse camera compared to Samsung's or LG's phones). So this is THE nexus for me.
Unfortunatelly Google doesn't sell it in Germany yet.
I want the Nexus 6P because my aging Nexus 4 is showing its age time and time again. I would really like to be in the big leagues by having the Newest, Latest and Greatest of the Nexus Family.
I NEED the Nexus 6P, because it's the perfect mix of my most loved phones; the HTC Legend (my first smartphone) and my (current) Nexus 5. Still love the look and feel of my Legend, but will never step away from stock Android!
