RIMM depended totally on corporate sales based upon the inititally sound basis of a solid, traditional design, bespoke encryption and professional functionality. And they didn't budge from that stance while iOS and Android increasingly eclipsed them as users expectations of what a smartphone could be, and more importantly should be increased exponentially.
Any company either so blind to technological advances or so arrogant with respect to their current market position deserves to fall by the wayside.
BB10 is radically new for Blackberry, but not for their user base. The bottleneck of routing data via in-house servers showed last year on at least two occassions that what was initially a security benefit had become an opertational risk.
Nokia is failing for quite different reasons, but failing it is. As will handsets based on Windows.
There is room for new technology in the smartphone market, but not in terms of beating the current two major players. The technology needs to come in the form of wearable technology, cloud based solutions and biometric accessories.
It is unlikely Blackberry or Nokia will be able to address this huge market for the simple reason their corporate ethos will not allow them to recognise the obvious. To dump what thery've got and has been their one trick pony for so long and start producing what the customers want.
