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 "iPad 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.
