Few people have heard of it, yet many consider John Blankenbaker's KENBAK-1 to be the first commercial personal computer.

Koss introduced these headphones over 40 years ago, and they remain affordable favorites to this day.

Osborne I - The First Portable Computer

Osborne 1
OhGizmo is running a piece on the Osborne I. This $1795 machine weighed in at 24.5 lbs and just fit under a standard airline seat, qualifying it as a 'portable.' It ran the CP/M operating system and was one of the first machines to come bundled with a huge array of software (Microsoft BASIC, SuperCalc spreadsheet, and WordStar).

Osborne earns a place in the Retro Thing Computer Hall of Fame for putting themselves out of business by pre-announcing a new 'executive' model many months before it was ready to ship. The result? Everyone said, "Ohh... I'll hold off buying until the new one's out." Predictably, sales plummeted and they filed for bankruptcy in 1983.
