David J. Smith, executive VP in charge of mobile computing, has resigned for personal reasons, a BlackBerry spokesman said. The move happened within the past few weeks, said a person familiar with the matter. The spokesman added that Mr. Smith “continues to come into work every day and is committed to working with BlackBerry through a proper transition.”
The highly-touted PlayBook stumbled out of the gate due to what many analysts considered a lack of core features and never sold well. Last year BlackBerry wrote down nearly $500 million in unsold PlayBook inventory.
