>> "Maybe longer than a year ago. But all the same, I don't know anyone that uses BBM now. If, as expected, Google launch their cross-platform messaging service at IO, it'll be in direct competition with BBM."

I know quite a lot of people that use Blackberry specifically because of BBM. I have however seen a lot of people (on all platforms) start migrating to Whats app and Viber so Blackberry might be too late. I'm excited to see what Google introduces but honestly I don't know 1 single person that uses any of their messaging platforms apart from Gmail. The two platforms used most in my experience are SMS and Facebook Messenger.
