I find it hard to imagine RIM dying entirely with the new move to use android applications. BBM is incredibly popular in large parts of Canada and it's hard to say what they'll look like if they finally get a halfway decent OS out. RIM will probably start manufacturing under android entirely if their next OS fails probably converting BBM and some of the nice features of that platform into applications with model restrictions (to all models made by blackberry) that come native on the phone. There are lots of business models under which they survive well. Yes, they're in a bad spot and their market share will erode for some time but I see them being able to become part of the many manufacturers on Android.
