As the mid-range laptop in its day, the PowerBook 140 was faster, and came with a larger display.

The PowerBook 140, unlike the PowerBook 100 and the Macintosh Portable, uses a NiCad battery.

Weighing in at 6.8 pounds, the PowerBook 140 zips along at 16 MHz on a Motorola 68030 chip and has 2 MB of RAM (expandable to 8 MB).
