As a 2 month long Xperia ZR user I can vouch for this phone. It is a rugged, waterproof phone - which earns its seal of approval from me. Custom roms to play around with(CM also present for this phone). Very good battery backup (1 and half days for my kind of use) and a very good camera (if you play with the manual settings). go for it. Build quality is good as well.
