Apple iBook SE, Graphite color, 2000.
From Wikipedia: The iBook was the first mainstream computer designed and sold with integrated wireless networking.[3] On the iBook's introduction, Phil Schiller, Apple's VP of Marketing, held an iBook while jumping off a height as data from the computer was transferred to another in order to demonstrate the wireless networking capability. The display bezel contained the wireless antenna, which attached to an optional internal wireless card. Lucent helped create this wireless capability which established the industry standard. Apple released the AirPort Wireless Base Station at the same time.
