SAN FRANCISCO (AFP) - Research In Motion on Tuesday released a long-overdue new operating system for its BlackBerry PlayBook tablet computer in the hope of gaining ground in a market led by Apple and Android gadgets.

PlayBook OS 2.0 software, available as a free download, comes just shy of a year later than it was originally slated for release by the Canada-based company.
The new PlayBook engine adds email, calendar and other productivity-related capabilities to the tablets.
'The new BlackBerry PlayBook OS 2.0 introduces a range of new communications and productivity enhancements as well as expanded app and content support,' said RIM senior vice president David Smith.
