Apple CEO Tim Cook unveiled the latest version of the iPad Wednesday, calling it an "amazing" device that will redefine breakthrough features the company introduced with earlier models.

The much anticipated tablet, officially known as the iPad HD, features a "stunning" display with about 3.1 million pixels on the screen.

There's an option for faster 4G wireless broadband through AT&T and Verizon in the United States. The third iPad will also have a 5 megapixel camera.

"Any company would be thrilled to have just one of these devices and we're lucky enough to have all three and the momentum has been staggering," Cook said.

Despite little difference between the new iPad and the previous iPad 2 model, Apple said continued consumer demand will make it a success.

The device will release March 16, but pre-orders are already underway on Apple's website.

The iPad HD will have the same introductory price as previous models, from $499 to $829 depending on storage and wireless capability.
