Research In Motion, the Canadian maker of the BlackBerry smartphone, introduced its first tablet computer on Monday at a developers’ conference in San Francisco. But in a return to its roots, the company said that the new device, the BlackBerry PlayBook, would be aimed mainly at business users.
The introduction of a tablet computer will not end criticism from some analysts that R.I.M. is now playing catch-up with Apple. But in a bid to distinguish the PlayBook from Apple’s iPad, Michael Lazaridis, R.I.M.’s co-chief executive, said that the new tablet contained several features requested by corporate information technology departments.
