The MacBook Air's graphics chipset used a portion of main memory as VRAM. Though reported as a 144 MB graphics system, the chipset actually used up to 160 MB of RAM, resulting in a maximum of 1888 MB of RAM available for system use in the base system.
Announced in January 2008, the MacBook Air was the thinnest Apple laptop yet released. It was positioned as a high-end ultra-portable system, and Apple had to make some sacrifices to get it there: At 1.6 GHz (1.8 GHz BTO), it was slower than other contemporary Apple laptops, its 2 GB of RAM was non-upgradable, it had a smaller, slower hard drive, no firewire ports, no ethernet port, a single USB port, no optical audio output, no audio input, and, for the first time since the PowerBook 2400, no internal optical drive.
There were sacrifices Apple did not make: the MacBook Air included a full-sized keyboard and screen, and an oversized trackpad, which supported many of the same multi-touch gestures introduced by the iPhone. To mitigate the connectivity and hardware tradeoffs necessary to make the MacBook Air so thin, Apple offered various accessories: an optional external 8x SuperDrive, a USB-to-ethernet adaptor, a USB 56kbps modem, and various micro-DVI adaptors.
The MacBook Air shipped in a single retail configuration, with a 1.6 GHz dual-core processor, 2 GB of RAM, and an 80 GB hard drive, for $1799. BTO options included a 1.8 GHz processor ($200), and a 64 GB solid-state drive ($999, later dropped to $599). The MacBook Air was replaced in October 2008 by the MacBook Air (Late 2008).
