I have purchased Sony Xperia Z white color in Feb 2014. Its an amazing phone having many pros and a few cons.
Pros:
1) Fantastic looking. Both flat shining surface gives the phone an amazing look.
2) Phone gripping is very nice. You can operate the phone with one hand
3) Superb quality from sony. Using this from more than two years and the phone had not hanged even once.
4) Water resistant. One of the first phone to introduce this feature.
5) Strong body and display. Fallen many a times, even from height, still the body and display was intact.
Cons:
1) Camera is not as good as previous sony phones.
2) Lag in battery back up.
3) Heats a bit in long use.
4) Does not support 4G.
Having a few cons, the phone is still much better than many phones available in the market at this price tag. Will definetely recomend to buy the same.
