Apple to launch iPad 3 on March 7

         SAN FRANCISCO: Apple Inc, the world's most valuable company, will hold a product event on March 7 in San Francisco, where it's said to be releasing the third generation of its best-selling iPad tablet computer.

           "We have something you really have to see. And touch," Apple said today in an invitation, which features a picture of an iPad screen. The new device will sport a high-definition display, run a faster processor and work with speedier wireless networks, people familiar with the product said last month.
