As someone who went back to BlackBerry when BB10 was launched, I'm not sure I'd buy this phone - in my opinion the Android UX is just so ugly and I'm not convinced that the Blackberry hub will work as well on Android as it does on BB10 (the two things I love most about my phone).
My Z10 is now 2.5 years old and I'm considering replacing it with a brand new one. I'll take a look at the Priv but my thoughts are it's too expensive and won't be as effortless to use as it would have been if it was running BB10.
