Flash Memory Storage
By replacing the standard spinning hard drive typically found in laptops (as well as desktop PCs) with flash memory, the MacBook Air delivers an almost instantaneous boot-up when you open the display, as well as faster application launches and snappier overall performance. Additionally, Apple has shed the enclosure that typically surrounds flash memory (usually about the same size as a standard hard drive), thus giving it a smaller footprint and helping to decrease the size of the MacBook Air.
Glass Multi-Touch Trackpad
With the addition of the smooth, glass Multi-Touch trackpad previously found on other MacBook models, the MacBook Air makes it even easier to navigate Mac OS X and your software applications. You can pinch, swipe or rotate images on the display screen with the brush of two fingers, or add more digits for a four-fingered vertical swipe to open Expose and quickly glance at all of your open windows.
Integrated FaceTime Webcam
You'll be able to easily connect with friends, family, and business colleagues using the MacBook Air's FaceTime camera, which is integrated into the thin bezel above the display. And with Apple's FaceTime application, you're not limited to video chats with other Macs--you can now make video calls to iPhone and iPod touch users (Wi-Fi connection required for mobile users).
Intel Core 2 Duo Processing
Combining fast processing speeds with power-saving features, the Intel Core 2 Duo processor provides greater multitasking performance by combining two independent processor cores while also reducing power requirements and saving on battery life. This Intel Core 2 Duo processor has a 1.86 GHz processor speed, fast 1066 MHz front-side bus (FSB), and 6 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)
High Performance Graphics
Powered by the NVIDIA GeForce 320M graphics card, the MacBook Air allows you to view flawless video in full screen HD and play the latest games with fast frame rate. It's a great match to editing video masterpieces with iMovie and managing your photos in iPhoto, and it comes with 256 MB of DDR3 SDRAM that's shared with main memory.-13.3-inch LED-backlit glossy widescreen display with a 1440 x 900-pixel resolution
