I'll save you the time I just wasted reading this rather lame, somewhat biased and not particularly enlightened review:
BlackBerry Passport Review - Enough to Keep Fans Hanging On? | TechnoBuffalo
The reviewer gave it a rating of 7.0PROS
Great battery life
Solid Camera
BlackBerry Blend is Awesome
Sharp screen
CONS
Bizarre form factor
Three Row QWERTY Not as Good as a Four Row
Software Bugs
Still a poor selection of apps
I think he deserves a 6.0 for his run-of-the-mill effort.
