The Apple MacBook Air "Core 2 Duo" 1.86 13-inch model from Late 2010 operates with a 1.86 GHz Intel "Core 2 Duo" processor (SL9400), which features two independent cores on a single chip, a 6 MB on-chip shared level 2 cache, and a 1066 MHz frontside bus.
It is configured with 2 GB of 1066 MHz DDR3 SDRAM integrated on the motherboard (with a 4 GB option available only at the time of purchase), either 128 GB or 256 GB of flash storage, and an NVIDIA GeForce 320M graphics processor that shares 256 MB of DDR3 SDRAM with the main memory. Also included are an integrated "FaceTime" video camera, a non-backlit full-size keyboard, and a 13.3-inch widescreen TFT LED-backlit active-matrix "glossy" display with a 1440x900 native resolution. These components are housed in an exceptionally thin (0.11-0.68 inch), 2.9-pound aluminum case.
Connectivity options comprise AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, an SD card slot, dual USB 2.0 ports, analog audio out, and a Mini DisplayPort that supports video output to an external 30-inch display. This model lacks an internal Ethernet port (an external adapter was offered as a US$29 upgrade), as well as Firewire and optical audio in/out.
The MacBook Air "Core 2 Duo" 1.86 13" (Late 2010) introduces a completely new chassis compared to its predecessors, doing away with the "fold-down" port door and incorporating an "inertial" multitouch trackpad. It also has significant internal differences. While it maintains the onboard RAM and lack of an optical drive like earlier models, it now includes flash storage not intended for user upgrades and multiple internal battery cells that are also not designed to be replaced. Apple highlighted that the flash storage enables this MacBook Air to deliver "instant on" responsiveness, offer up to 30 days of standby time, and achieve a thinner profile with extended battery life.
