Believe it or not, it's already time to pawn your iPad 2 for a new one. Apple's all-new iPad 3 ($500-$830) is ready to hit store shelves equipped with features that make your current one obsolete a has-been. About 0.6mm thicker and 0.05 heavier than its predecessor, the iPad 3 features Apple's A5X processor with quad-core graphics, as well as high-definition Retina Display with 2048 x 1536 resolution, to make your apps run faster and look even better. It's also equipped with the new 5-megapixel backside-illuminated iSight camera with auto-exposure, auto-focus and 1080p stabilized HD video recording, stronger battery, iPhoto app, updated iMovie and GarageBand, and built-in support for AT&T's and Verizon's 4G LTE networks (sorry, Sprint).
