Apple today announced the third-generation iPad at an event in San Francisco. The device's main feature is a 2048x1536 Retina Display, twice the resolution of the iPad 2, rated at 264 pixels per inch; existing apps will be upscaled automatically. Color saturation is said to be 44 percent higher. The tablet also makes the switch to a new quad-core processor, the A5X, which Apple says is built with the Retina Display in mind. Interface-wise the tablet has been improved with features like voice dictation.
