Build me this...
What I'd like to see is a good phone with all the features of this, but with wireless charging and no external ports... with bluetooth LE etc you don't need a headphone socket, USB data sync is long since redundant, and the SIM and SD cards slots should be inside the back cover.
So ditch all the external connectors, which means the phone can be 100% waterproof and dust-proof.
And even if it means making it a little thicker, (more room for battery?) for the love of god recess the camera lens to protect it... having it sticking out just gets it scratched.
