This is something I actually need and want so bad! My current phone is a bit broken (most of the time the bottom part of the screen doesn't notice touch at all) and Z2 has everything I need. Its waterproof and dust proof too so it wont brake if I have to ride (11km) home in rain (I have to ride moped because in finland u have to be 18 to ride car and I'm 16) and I also like listening music and taking pictures and videos so front speakers would be good for music and camera has everything I need and the slowmo feature makes even better for me so I can watch tricks in slow mo and see what I should do to make it look and feel better.
Sorry for bad english. Hope you can still read it!
