This laptop features an Intel second generation Sandy Bridge Intel Core i5-2467M processor (1.60 GHz), 4GB DDR3 RAM, a 128GB SSD and for graphics processing, you have the Intel HD 3000 graphics. You can also make FaceTime calls from your MacBook Air to an iPhone 4S, iPhone 4, iPad 2, iPod touch, or another Mac running FaceTime for Mac. The price of 11-inch MacBook Air starts at $999.00 and 13-inch starts at $1,299.00.
