guess what
i browsed every single stall/shops in melaka frm dp to aeon
and none is selling xperia z cases
the maximum they only carry one type which is the flip case
unlike iphone5 and samsung xperia z is sooo low profile

depends.
I bought it despite I know that the Z1 is coming out. I do not need all the processing power of s800. and  the saving by not getting the Z1 woyld most likely use for that camera extension.

water proofing is  good. would never realized it usefulness unless u try one, for example not having to worried about putting the phone on top of table while drinking or talking in the rain nor watching a movie in the shower.
