How would you change Sony's Xperia Z?

Sony's been trying to reinvent itself, and in doing so, is hoping that we can put these turbulent last few years behind us. Nowhere is this more evident than in the company's smartphones, like the Xperia Z. The Z was the first "omnibalance" phone, and the first not to be associated with the company's former partnership with Ericsson. It brought along a 1080p display, water resistance and, surprisingly for a phone significantly more expensive than a Nexus 4, pretty crappy battery life. That fact alone was enough for it to register a measly 80 score from our reviewer, but did you agree with them? This is How Would You Change, where you're encouraged to leap onto our forums and talk us some smartphone.
