the real trend
I find the news of ppl moving from blackberrys to other devices strange. My experience both in corporates and the general population is that blackberrys are becoming more popular. The qwerty on bb's helps people to connect using type quicker and deeper. When the novelty of apps is gotten past people still use phones mainly for communicating, voice and text. For example I know loads of teens dropping their iphones for bb's because of bbmessenger (something taken up by bb in their latest ads). If u want to read ebooks etc a larger form factor is needed than a smartphone to be a used seriously. Its a question of how u define markets, in the pure touch arena android and iphone are ahead, but in the physical key stakes bb leads.
