A best bet is the 2.9-lb. Apple MacBook Air Intel Core 2 Duo 2.13GHz 13.3" Notebook (pictured), model no. MC905LL/A, for $1,148.99. This $25 mail-in rebate cuts it to $1,123.99. With free shipping, that's the lowest total price we could find by $86, although we saw it for $25 less five days ago (since expired). This previous-generation model features an Intel Core 2 Duo 2.13GHz dual-core processor, 13.3" 1440x900 LED-backlit LCD display, 4GB RAM, 256GB SSD, NVIDIA GeForce GT 320M video card, webcam, 802.11n wireless, Bluetooth 2.1, and Mac OS X 10.6 Snow Leopard (with free Mac OS X 10.7 Lion upgrade).
