The Xperia z2 is such a sick. Front facing speakers are amazing. Also, I really Like the brand skins. Was actually thinking about buying one for my iPhone but I'm going to be selling it soon.
The display on this phone is just ridiculous. It is really awesome, but I would have to say that my favorite part of the phone is the really really slim bezels. Makes the huge 5.5 inch screen usable for the average person.
