Intel Core i5 and i7 processors.
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 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
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
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.
Multi-Touch trackpad.
The Multi-Touch gestures in OS X Lion make everything you do on MacBook Air more intuitive, direct, and fun. And the spacious Multi-Touch trackpad is perfectly designed for them, whether it’s a three-finger swipe to activate Mission Control or a four-finger pinch to see all your apps in Launchpad. Gesture responses in Lion are smooth and realistic. So when you’re scrolling up and down a web page or swiping from one full-screen app to another, it’s almost like you’re touching what you’re seeing.
Display, camera, and speakers.
Long-lasting battery.
Instant on. Even after a month off.
Things like browsing the web, editing photos, and watching videos. Get up to 5 hours of battery life on a single charge on the 11-inch model and up to 7 hours on the 13-inch model. Put MacBook Air to sleep, and it enters standby mode to conserve battery life for up to 30 days.3 When you come back to your MacBook Air and open it up, it’s on in an instant.
Connectivity.
You’re free to go.
MacBook Air features 802.11n Wi-Fi and Bluetooth 4.0 technology. Wireless connectivity allows you to browse the web, send email, and print documents no matter where you are.4 MacBook Air weighs almost nothing, so you can go from room to room, dorm to dorm, or cubicle to cubicle and stay connected. Being wireless also means you can download apps from the Mac App Store anytime you want. With thousands of Mac apps available for download with just a few clicks, you don’t have to bother with going to the store to buy software on disc or worry about a growing pile of CDs and DVDs. Apps download instantly right on your Mac. If plugged in is what you want to be, MacBook Air has you covered there, too. Two USB 2.0 ports, an SD card slot (on the 13-inch model), and a headphone port give you plenty of options. And the Thunderbolt port connects to the new Apple Thunderbolt Display and high-speed Thunderbolt peripherals such as external hard drives.
