Apple's new iPad unveiled

Apple has unveiled a new iPad with a high-definition screen.

It said the resolution of the display was 2,048 by 1,536 pixels. The tablet is also powered by a new A5X chip with improved graphics performance.

But some critics have expressed disappointment that the product has not been more fundamentally updated.
