Apple 11.6" Air MacBook: Core i5 1.4GHz, 4GB Memory, 128GB Hard Drive, Mac OS X (Refurbished)

Up to 3x faster Wi-Fi.

MacBook Air supports ultrafast 802.11ac Wi-Fi. When connected to an 802.11ac base station — including AirPort Extreme and AirPort Time Capsule — wireless performance is up to 3x faster than with the previous generation of Wi-Fi or MacBook Air with 802.11n Wi-Fi
2. And your Wi-Fi range improves as well. With Bluetooth technology, you can connect MacBook Air to Bluetooth-enabled devices like speakers and headphones. Even without all the wires, you’re totally connected.
Backlit keyboard. What you see is what you type.

As incredibly compact as MacBook Air is, it still manages to fit a full‑size keyboard that makes typing as natural as it is comfortable. And the keyboard is backlit, so you can type with ease in even the dimmest light. A built-in ambient light sensor detects changes in lighting conditions and adjusts the display and keyboard brightness automatically. From a seat in a sunny café to a seat on a cross‑country red‑eye, you’ll always have the perfect lighting for any environment.
Thunderbolt and USB 3.

With the lightning-fast Thunderbolt port, you can connect your MacBook Air to the latest devices and displays, like the Apple Thunderbolt Display. But that’s not the whole story. MacBook Air also comes equipped with two USB 3 ports, so you can connect the latest USB 3 devices and all your USB 2 devices as well. With just a few connections, MacBook Air transforms from an ultraportable notebook to a complete workstation.
Fast all-flash storage. Ready. Set. Done.

Part of what makes MacBook Air so responsive is that it’s designed entirely around flash storage. Not only does this make MacBook Air much lighter and more portable than traditional notebooks, it also provides faster access to data. This PCIe-based flash storage is up to 9x faster than a traditional 5400-rpm notebook hard drive3. So when you flip open MacBook Air, it’s ready to go right away. Even after a month in standby mode, the screen springs to life.
Up to 9 hours of battery life.

Thanks to compact all-flash storage in MacBook Air, there’s plenty of room for a big battery. Working together with the power-efficient fourth-generation Intel Core architecture, this battery can post some impressive numbers. The 11-inch model gets up to 9 hours of battery life on a single charge. Put MacBook Air to sleep for more than 3 hours, and it enters standby mode to conserve battery life for up to 30 days4. And if you enable Power Nap, you’ll continue to receive new email and calendar invitations while your computer is asleep.
