There is no doubt their strength is software coupled with security ( perceived of actual, I am not sure which of maybe both)......but the problem is Apple, Google, and a host of others, not to mention Mercedes Benz have thrown billions at this, and started almost a decade ago.....with BB's comparative puny resources in this endeavour....I am not convinced they can compete....but Mr. Chen is a wizard and I would never count him out....but the deep pockets and experience others have in this field worry me for BB's efforts .
