Today, RIM unveiled its new Blackberry 10 operating system and a pair of corresponding handsets – one entirely touchscreen, and one with the beloved physical keyboard that Blackberry users swear by. While the RIM stock has risen in value in anticipation of this fateful day, the success of Blackberry 10 is far from certain. Many consider Blackberry 10 to be RIM’s last chance at rescuing its once-innovative devices from becoming completely obsolete, but to do so, Blackberry 10 has not only persuade its few remaining fans to upgrade to something radically new and presumably different, but also distinguish itself enough from competing smartphones to attract new fans.

Heather Kelly at CNN evaluates the innovations of Blackberry 10, but concludes that, despite its relative thoroughness at addressing the concerns that have been raised with against earlier Blackberry operating systems, “there’s no guarantee it will work.”

Call me biased (yes, I am an avid iPhone supporter), but judging from the sheer competitiveness of the smartphone market and the substantial disintegration of RIM, not only in terms of Blackberry technology itself, but, perhaps even more disparagingly so, in its reputation, I think that the Blackberry 10 operating system and its corresponding devices are too little too late to espouse the comeback RIM is hoping to make. Does anyone have a differing opinion?
