GoKawiilApple's 1998 iMac G3 confirmed as first mainstream USB-only computer
A tech trivia feature identifies the original iMac G3, released in 1998, as the first widely used computer to drop all legacy ports in favor of USB exclusively. The machine shipped with two USB 1.1 ports and no ADB, serial, SCSI, or floppy connectors, while retaining Ethernet, a modem jack, and audio. The piece also examines near-misses like Sony's VAIO 505 and Compaq's iPaq Desktop, which came later or kept some legacy ports.
