The Apple MacBook Air "Core 2 Duo" 1.86 13" (NVIDIA/Late 2008) 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 128 GB Solid-State Drive (SSD), 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 Ethernet (an external adapter is available), Firewire, and optical audio in/out.
The MacBook Air "Core 2 Duo" 1.86 13" (NVIDIA/Late 2008) uses the same housing as the original model -- with the same 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, but it has a number of internal improvements as well including a marginally faster processor (in this model), faster NVIDIA graphics, a faster architecture with a faster system bus, and faster memory, and a larger L2 cache. It additionally ships equipped with a larger SSD and swaps the mini-DVI port for a new Mini DisplayPort standard.
