If you are still using the original iPad and looking for any excuse to go with the iPad 3, let this review be all the excuse you need. The iPad 3 is light years ahead of the original iPad, with a major boost in graphics, processing power, memory used for apps and data connection speed in addition to those dual-facing cameras.
But if you already own an iPad 2, you can easily skip this generation of the iPad. The upgraded graphics are nice, but 99.995% of all apps will still support the 1,024 x 768 display. It will take a few months for the Retina Display to see any major support in the app store, since games and apps must be made with both the graphics processor and the upgraded resolution in mind. And by the time we'll really start seeing the benefits of the new iPad, the iPad 4 will be just around the corner.
