I've been a blackberry user for 8+ years (enterprise/personal) and I must say BB knocked it out of the park with this Passport!!!!
I will admit, I've been on the darkside for the past year with my Nexus 5. However I always felt empty, kind of like losing a good girlfriend. That was until this morning when I got my Passport, WOW I feel so alive again!! Keyboard, flicking, voice prompts and best of all BB BLEND!!!!!
I've been putting this phone thru the ringer all day, downloaded all my files, apps, active synced all my email accounts, sent 30+ emails, 20+ phone calls etc... and I still have 73% battery left :). Using the assistant while driving has been an unbelievable experience.
Bottom line, this thing is fantastic; Great Job BB!!!
BTY - I'm on AT&T getting full LTE
