I actually just got off the phone with my dad who has had a BlackBerry for the last 10 years and just replaced his with an Android phone (Samsung something, I believe) last week. He said he finds it much easier to use and likes it more. It's well noted that brand preference is largely irrational and thus any amount of anecdotes means very little. What it does mean is that BlackBerry is likely to continue to decline in market share unless they revamp their OS to be more app friendly (and redo their app store to make it worthwhile), but they will probably never go away. My best guess would be that they act stubbornly (as large companies often do) and decline in market share for awhile before deciding to sell to a larger player.
