Pros Had a really good time with it lately at a party. Worked well with my friend's android too. If you're a Blackberry user I highly recommend it. If you have a Playbook even better. Also worked well in the car.
Cons If you have an iphone its not for you since apple has not yet embraced NFC tech. Hopefully iphone 5 will.
Summary RIM needs to create more than just a great phone but a great Blackberry experience by leveraging the power of their technology. This is a good step in that direction.
