Upgraded from a Q10 to a Z10.  Very likely the Z30 will be my next phone, but that will be a while.  Z30 is one of BlackBerry's most popular phones.  I'd get a Passport in a heartbeat if Verizon offered it.  Looking forward to BB10 OS 10.3 being ready for prime time.  Hopefully by the time summer rolls around, Verizon customers will get it.
