At its special press event today, Apple introduced the fourth-generation iPad. Physically almost identical to the third-generation iPad it replaces, this iPad features a new A6X chip, promising double the performance of the A5X for CPU tasks, as well as a new front-facing FaceTime HD camera with 720p video and 1280x720p still photo support. Other new features include Wi-Fi that’s claimed to be twice as fast, support for new LTE carriers including Sprint in the United States, and the Lightning connector. The fourth-generation iPad retails for the same prices as the third-generation model, ranging from $499-$829. Pre-orders begin on October 26 with sales of the Wi-Fi beginning November 2 and the LTE model coming about two weeks later. The third-generation iPad has been discontinued.
