Apple to hold March 7 event, new iPad expected

Apple sent out invitations Tuesday to a March 7 press event expected to be the unveiling of the next generation of the hot-selling iPad tablet computer.

The invitations featured a picture of an iPad and the words: "We have something you really have to see. And touch."

The event is to be held at San Francisco's Yerba Buena Center for the Arts, where Apple has unveiled numerous products over the years.

Dow Jones-owned technology blog All Things Digital reported earlier this month that the "iPad 3" will be shaped like the current model, but run on a faster computer chip and have improved graphics.

Apple has sold more than 55 million iPads since launching the device in April 2010.
