It looks like such an amazing phone, and I'm definitely looking at picking it up soon. If only that camera was better! I played with one in the store yesterday and it really is bad. Even in a brightly lit room when you zoom in it had a lot of noise in the picture. I've been using a Nexus 4, and the camera of that isn't exactly spectacular either. As for the M8, specwise its gonna be hard to beat the S5. I like the look of the Z2 as well so that is probably worth looking into.
