One of RIM’s prize possessions is their BlackBerry Messenger (BBM) service – there are over 55 million users and many of them are loyal to the brand because it exists. How do you like the sounds of a “dedicated BBM key”? According to a leaked roadmap this is the direction RIM is heading towards and it’s actually VERY cool, not revolutionary, but very cool. This BBM key seems to be in place of the left-side convenience key and gives you instant access to BBM with a touch of a button. Very reminiscent of the dedicated Facebook button that found their way to a few HTC devices last year. At the least this addition will reduce the number of steps it takes to see if people are reading your messages.
