Apple Store offers its factory-refurbished 3rd-generation Apple iPad 64GB 4G + WiFi for Verizon or AT&T in Black or White for $499 with free shipping. That's $40 under last summer's mention of a new unit and the best price we've seen for any new 64GB 4G iPad. (It's $181 under the cost of a new unit today.) It's 9.4mm thick, weighs 1.4 lbs., and features a 9.7" 2048x1536 Retina display, A5x dual-core processor with quad-core graphics, 5-megapixel iSight camera with 1080p video recording, front FaceTime camera, voice dictation, 802.11n wireless, Bluetooth 4.0, up to 10 hours of battery life, and iOS 5.
Also available is the factory-refurbished 3rd-generation Apple iPad 32GB 4G + WiFi for AT&T in Black or White for $429 with free shipping. That's $251 under our August mention of a new unit and $113 less than the best we could find even for a used unit today. (Update: Out of stock.)
