BlackBerry CEO Thorsten Heins told Bloomberg that "in five years I don't think there'll be a reason to have a tablet anymore," and that tablets are "not a good business model." Which is maybe true if you sell PlayBooks and less so if you sell, say, 20 million iPads every three months.
Its like trying to say that a Desktop will die. We will still have a need for a stationary computer platform for work among other things. Tablets are a convenience, customers like convenient things.
I like BlackBerry, but that's a dumb thing to say. They did not do a good job with their tablet so that's how he feels. For his business strategy, you're right, don't focus on tablets but don't say stupid crap like that.
