Why did BlackBerry crumble?

here are some random disjointed thoughts: 1) it ain't over til it's over. 2) even if it is over your Z10/Q10 still has a lot of life left in it. I still have and lovingly use my Nokia N9, and heck there are still people clutching to their Newtons! 3) it's not necessarily a smartphone duopoly. Not just because of Windows Phone, Tizen etc but also for the emergence of smaller, community powered niche devices like Jolla Sailfish and Ubuntu. There will always be a ticket out of the "duopoly"...I for one can't wait to get my Jolla.
To me it is a Phone with Email capability. And i could not understand how this was a selling point. And that was long before iPhone was introduced.
