I recently upgraded from a legacy 9900 to The Z30, it is literally the best move I have ever made (mobile connectivity).
The Hardware is flawless in terms of esthetics, I'm in no position to comment on durability for obvious reasons but coming from Bold8310 - Bold9780 - Bold9790 - Curve9320 - Bold9900 I have all the faith in Blackberry's ability to take the occasional bump and knock.
The UI of the OS is packed full of daily delights as the more you use it the more the Z30 fits your style of use and not just in typing but from Settings to Options the Z30 really does adjust itself to keep you moving (stumbled on that one).
Pls don't be swayed the undue negative publicity in the USA, the Z30 is more than capable to meet and excell at any task put to it.
Proudly South African.
5star Z30
