same idiocy as MS.
it's either user-centric or it isn't. BB catered to "business", but that meant IT. the users, managers, switched privately to iPhones. then demanded them from IT. boom, headshot.
BYOD is what kills "business-centric".
BB realized that, tried to position BBM as a user centric thing. too late. and schizo, as the playbook slogan "amateur hour is over" showed.
