When Apple or even Google (Android) comes up with a new product or the tiniest update/upgrade for an existing product, everyone goes hyper irrespective of the relevance.
BlackBerry puts forth a tried and tested and much loved product for the rest of the world and any hype is frowned upon, their marketing mistakes are blown up to look like management blunders that could cause another 'Depression'.
The point is that BBM is a great product. It is one of the best if not the best messenger service out there. It beats the others in speed and efficiency and more importantly it is reliable and it is secure and private. Just knowing your email ID or phone number does not put you at risk of being a spam target... The BBM PIN ensures that.
So be glad that BBM made it to the other platforms and stop whining about the hype.
Enough with the stupid jokes already!
