"In five years I don’t think there’ll be a reason to have a tablet anymore." Those comments from Thorsten Heins have set the tech press abuzz. Many note Heins' remarks, which follow past comments about BlackBerry (BBRY +4.3%) taking a cautious approach to tablets, seem strange given the market's staggering growth. But an explanation appears to lie in March remarks from Heins about BlackBerry pursuing "a mobile-computing experience" that allows users "to carry one computing device." Instead of competing in a hotly contested tablet market, BlackBerry seems to be pushing a vision of (BB10) smartphones paired with PC/tablet docking peripherals. Time will tell if they'll be more successful here than Motorola.
