Apple rolled out a high-definition new iPad on Wednesday with a faster processor, a better camera and a display screen that promises to be dramatically sharper than the current model, the iPad 2.

The new 9.7-inch display screen will feature a “retina display” of 2047 by 1536 pixels, compared with the current model’s 1024 by 768 pixels.

The new iPad will be available in the United States and 9 other countries March 16 and cost the same as the iPad 2 — from $499 to $829 based on storage capacity and Wi-Fi capacity. Pre-orders were opened at Apple’s online store on Wednesday.
