The Apple Store offers its factory-refurbished, 2.3-lb. Apple MacBook Air Intel Core 2 Duo 1.4GHz 11.6″ Widescreen Notebook, model no. MC505LL/A, for $699 with free shipping. That’s tied with our mention from five days ago as the lowest total price we’ve seen for a MacBook Air with an Apple warranty. (We did see an open-box model with a 90-day 3rd-party warranty for $16 less in August.) Features include an Intel Core 2 Duo SU9400 1.4GHz dual-core processor, 11.6″ 1366×768 LED-backlit widescreen glossy LCD, 2GB RAM, 64GB SSD drive, 802.11n wireless, Bluetooth 2.1 + EDR, multi-touch trackpad, iSight webcam, and Mac OS X 10.7 Lion. A 1-year Apple warranty applies, the same as new Apple laptops.
