The Apple Store offers its factory-refurbished, 4th-generation Apple iPad with Retina Display 32GB WiFi Tablet in Black (pictured), model no. MD511LL/A, for $549 with free shipping. That's $49 under the best we could find for a new unit and the lowest total price we've seen for this model with an Apple warranty. (We saw it for $49 less three weeks ago, but it only had an unclear 90-day warranty.) Sales tax is added where applicable. This current-generation iPad is 9.4mm thick, weighs 1.4 lbs. and features a 9.7" 2048x1536 Retina display, A6X dual-core processor with quad-core graphics, 5-megapixel iSight camera with 1080p video recording, 1.2-megapixel HD FaceTime camera, voice dictation, 802.11n wireless, Bluetooth 4.0, Lightning connector, up to 10 hours of battery life, and iOS 6. A 1-year Apple warranty applies (the same as with new models).
