Apple MacBook AirThe Apple MacBook Air "Core 2 Duo" 1.86 13" (Mid-2009) is powered by a 1.86 GHz Intel "Core 2 Duo" processor (SL9400) with two independent processor "cores" on a single chip with a 6 MB on-chip shared level 2 cache running on a 1066 MHz frontside bus.

It features 2 GB of onboard 1066 MHz DDR3 SDRAM, a 120 GB hard drive (4200 RPM), a NVIDIA GeForce 9400M "graphics processor with 256 MB of DDR3 SDRAM shared with main memory", an integrated iSight video camera, a full-size backlit keyboard with ambient light sensor, and a 13.3" widescreen TFT LED backlit active-matrix "glossy" display (1280x800 native resolution) in a razor thin (0.16-0.76 inch), three pound, aluminum case.

Connectivity includes AirPort Extreme (802.11a/b/g/n), Bluetooth 2.1+EDR, a single USB 2.0 port, analog audio out, and video out capabilities (Mini DisplayPort) that support an external 30" display. It lacks internal Ethernet (an external adapter is provided) and lacks Firewire and optical audio in/out as well.

The MacBook Air "Core 2 Duo" 1.86 13" (Mid-2009) uses the same housing as earlier MacBook Air models -- with a 13.3" display, full-size keyboard and single button, "three-finger" trackpad. Internally, it likewise lacks an optical drive, the battery is not designed to be removable, and the memory cannot be upgraded beyond the onboard 2 GB.

However, compared to the "NVIDIA/Late 2008" MacBook Air series, the "Mid-2009" models have better battery life (5 hours compared to 4.5 hours), include the Apple 10/100Base-T Ethernet adapter standard, and were unveiled at considerably lower prices.
