This is the newest version of the MacBook Air. It has an 11.6-inch display with a 1366x768 resolution, Intel Core i5 dual-core processor clocked at 1.7GHz, 4GB of DDR3L-1600 RAM, 64GB flash storage, Intel HD Graphics 4000, 720p FaceTime HD camera, mini DisplayPort output, HDMI output, two USB 3.0 ports, SD card slot, 802.11n Wi-Fi, Bluetooth 4.0, backlit keyboard, and other amenities.
It's also on sale at Amazon for $900 and free 2-day shipping with a Prime account, though it's still cheaper at Best Buy, even after factoring in sales tax.
Whether or not it's a great buy depends on how badly you want to roll with Apple. At $800 and only 11.6 inches, it's still pricey, especially compared to Windows 8-based Ultrabooks. For $450, Best Buy sells an Asus 11.6-inch Ultrabook with a touchscreen display. It's rocking a hard drive (500GB) and slower processor (Core i3), but it's nearly 50 percent less expensive.
It's all food for the thought if you're shopping an ultra-thin laptop.
