Blackberry Z10 to Q5 to Q10 and finally Z30!
Just got my Z30, still missing the keyboard and universal search in my previous (Q10) however I can say this is so far the best Blackberry ever made.
Pros:
*Feels very well built (compared to Z10)
*AMOLED screen high quality
*Long battery life
*Wifi direct, Miracast
*HDMI out
*USB OTG
*BB10 is a very nice fast and stable OS
*MicroSD slot
Cons:
*Camera is just 8 Mpx and not too good in night time. Daytime is ok'ish.
*Battery cannot be replaced
*App selection, but this can be fixed by installing any android APK directly in the machine or installing Snap or the Amazon Appstore.
A very happy and satisfied Blackberry customer here.
By the way, previous phone (before the Q10) was the Q5 and a Nokia Lumia 1020. WP8 is a P.O.S., stay away from that closed OS (pretty much like iOS back in iOS 3.0).
