Apple will unveil a new version of its market-ruling iPad table computer in March, according to a report in Dow Jones-owned technology blog All Things D.

The latest in an ongoing stream of Apple rumors cited unnamed sources as saying that an " 3" will make its debut at an event the California company will host in San Francisco in the first week of March.

The next-generation iPad will be shaped like the current model, but run on a faster computer chip and have improved graphics on par with those seen in Apple's coveted iPhones, according to the blog.
