I've told Blackberry a handful of times that the Z30 is what the Z10 should have been as far as hardware goes. Screen size differences notwithstanding, the Z30 feels 100x better than the Z10. The features are more complete and there was no reason for Blackberry to have put out (looking back) a half finished product that is the Z10. USB host, wifi direct/miracast, BT4.0, stereo speakers, reasonably sized battery, all things that the Z10 should support/have and doesn't. Even with the 10.2.1.x leaks on the Z10 it felt 50x better than the Z10 that was shipped to me. Stock Z30 was at least 25x better simply because of the features I named above, but 10.2.1.x is when it started to shine. I do have criticisms for the Z30 but none that will change (location of SIM and SD cards and the cover for both, non-removable battery shouldn't be an issue but when loading leaks a battery pull is sometimes necessary).
I have the Z30. Do I care about USB host, miracast and Wifi direct.....NO
As for the battery, yes I do care. But go look at my mom or dad's z10's. They can go 24 hrs np. Lol
Z30 has all the dudads for you, but 90% of the people using bb10 will never know they exist.
People seem to forget the Aristo as it was know back in the day was supposed to be BlackBerry's high end phone so of course it had to be a major improvement over the base model Z10. Only mistake in the Z10s design IMO is it should have not included a removable battery so it could have been higher capacity. But of course I like a lot of BB users were so used to battery swapping with BBOS that we demanded removable batteries.
I am switching from IOS to BB10! What I would like to say is that BB10 Z30 beats the iphone 5s in its battery life test! BlackBerry Z30 is meant for heavy users and on the go users! It is only lack of apps support! Z30 is really really good and outperform the iphone 5s!! RTOS is good! I love the QNX in Z30!!!
Don't forget the FM radio. but once you use Miracast it is pretty freaking cool and convenient. I am sure wireless charging on all Z30 and not just the VZ one would have been better and more used.
