RIM confirms release of new tablet to rival iPad

BlackBerry maker Research in Motion unveiled the PlayBook, a tablet computer, at a developer conference Monday. The tablet market is so far dominated by Apple (AAPL, Fortune 500) and its popular iPad, but other tech companies are trying to cash in as well. "Every successful professional has a great PlayBook," said Mike Lazaridis, co-chief executive of RIM, at the BlackBerry Developer conference in San Francisco. CNN
