CUPERTINO - (AP) - Apple is revealing a new iPad model. New features include a sharper screen and a faster processor.

It will go on sale March 16.

Prices aren't changing from previous models. They will start at $499. Versions capable of accessing cellular networks will cost $629 to $829. For the first time, the iPad will be able to access the faster 4G cellular networks.

Apple says the new display will be even sharper than the high-definition television set in the living room. The company says it will show more saturated colors than previous models.

Apple says the new model also will be four times faster.

Apple Inc. CEO Tim Cook says, "We are taking it to a whole new level and are redefining the category that Apple created with the original iPad."
