January 15, 2008: Steve Jobs shows off the first MacBook Air at the Macworld conference in San Francisco, calling the revolutionary computer the “world’s thinnest notebook.”
The 13.3-inch laptop measures only 0.76 inches at its thickest point and 0.16 inches at its tapered thinnest. It also boasts a unibody aluminum design, thanks to an Apple engineering breakthrough that allows the crafting of a complicated computer case from a single block of finely machined metal.
In a brilliant piece of showmanship during the MacBook Air launch, Jobs pulls the super-slim laptop out of a standard interoffice envelope.
