11-inch MacBook Air (Mid 2011): 1.6GHz. 2-Core i5, 4GB, 256GB, Silver - MC969N/A

Intel Core i5 and i7 processors.
Performance that shouldn’t be taken lightly.
Both the 11- and 13-inch MacBook Air now feature the latest generation of Intel processors, the Core i5 and i7. With speeds up to 1.8GHz and faster memory, the new MacBook Air gains up to 2.5x the processing performance over the previous generation.1 MacBook Air also features the Intel HD Graphics 3000 processor, which includes an on-chip engine for video encoding and decoding. That means you experience video playback and FaceTime calls that are smoother, more responsive, and more true to life.

Thunderbolt I/O.
Lightning-fast data transfer.
With one port, MacBook Air gives you access to a world of high-speed peripherals capable of transferring data up to 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0. Or use the Thunderbolt port to connect the new Apple Thunderbolt Display and transform your ultracompact MacBook Air into a complete desktop workstation. Power over 4 million eye-popping pixels while enjoying some major benefits: Gigabit Ethernet, FireWire 800, an additional Thunderbolt port, three USB ports, a FaceTime HD camera, 2.1 stereo sound, and a built-in microphone. The display even charges your MacBook Air, so there’s no need to unpack and unravel your power adapter. With two quick connections — the MagSafe power cord and the Thunderbolt cable — you’re up and running in seconds. Unplug them, and you’re on your way just as fast.

All-flash storage.
Instant-on gratification.
Devices like iPhone and iPad have already demonstrated the advantages of flash storage: reliability, speed, and efficiency. So the decision to use flash storage in an ultracompact notebook like MacBook Air made perfect sense. With flash, your computer starts up in almost no time and accesses data quickly. Flash also gives MacBook Air the astonishing ability to remain in standby mode for up to 30 days.3 Which means your MacBook Air snaps to in an instant, whether you open it tomorrow, next week, or next month.

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 now 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.
