That phone is the small evolution of HTC's smartphones design. The whole phone is made of metal. The edges are flat and for me it's OK. Phone looks modern because of that, also elegant and nicely like always :D

Summary
So so so... In my opinion HTC did really good work. The facelift of that series went very well. phone has all what you want from the premium leauge. Great CPU,GPU and 4GBs of RAM, also camera is just great. Battery it's good, but not excellent. You should get like one and a half day at medium-use. Multimedias are grat in this phone. In Poland phone cost like 3000PLN (Lifestyle version). For Lifestyle version it's too much, but for that version that I describing it's OK. Maybe 200-400PLN less and will be great :P
