Apple has re-released the fourth-generation iPad. The model replaces the aging iPad 2 in Apples lineup. The fourth-generation iPad is priced at $399 —the same price as the iPad Mini with Retina Display, and $100 less than the iPad Air — and is only available with 16GB of storage. The decision to replace the iPad 2 with the iPad 4 means that all of Apples iPads are now using the companys Lightning connector and also makes the iPad Mini the only tablet from Apple not to feature a Retina Display.
