Aside from the single capacity choice, there aren’t any changes to the device. This new model replaces the iPad 2, which has been around since the days of the 30-pin connector. The newer version includes Apple’s custom dual-core A6X processor, a 5 MP iSight camera, and 1.2 MP FaceTime camera.
The iPad 4 is available at $399 for the Wi-Fi model, putting it at the same price as the previous iPad 2. The cellular model costs $599. Both are available on Apple’s website and in retail stores.
