Look at the back of it. Is that... leather? I doubt it, but it seems that Samsung is FINALLY trying to change their design. I mean really, currently all their phones look the same.

On the phone itself: why would I need curved screen? Whole 5,7 inches of it? For me perfect size is about 4.3 inch - slightly larger than N9. It seems to me Samsung tries to say "Hey, look people, we made world's first phone with curved screen, just because we can". I haven't heard anyone saying "Darn, I wish I had a phone with curved screen". It's just pointless IMO.
