The iPad (3rd Generation) (colloquially called simply "the new iPad" at its launch) features a higher-than-HD screen, otherwise known as a Retina display, with a 2048 x 1536 resolution. It has 3.1 million pixels. "The most ever in a mobile device." Phil Schiller says, "This presents a problem for us in presenting it to you. For the first time, an iPad has a higher resolution than the entire display behind you...that's a fun challenge." That is crazy!
The new iPad also has a dual core A5X processor with quad core graphics.
The next big feature was an upgrade to the camera on the iPad. The rear facing camera is 5 megapixels, enough to shoot full 1080p video. The camera is the same setup as the iPhone 4S. It features a 5 element lens, a hybrid IR filter, and video stabilization.
Apple also released the iPad on 4G LTE. Unfortunately, there are two different versions of the iPad, one for Verizon and one for AT&T. However, there will still be 3G support, so when you are roaming, you can use 3G networks. Apple also announced that you can create a personal hotspot with your iPad, but only if your carrier supports it.
