The 33 MHz PowerBook 150 replaced the 25 MHz PowerBook 145b in July 1994. It offered faster performance at a lower price and was the final model in the 140 / 145 / 145b /150 line of economical PowerBooks.

The 150 was also the lightest of the line, and its battery was rated at 2.5 hours, about 30 minutes longer than previous models. Finally, the 150 sports a 640 x 480 display, the same size number of pixels as a standard monitor in those days.

Using the same memory modules as the PowerBook Duos, the PB 150 was far more expandable (to 40 MB!) than other PowerBooks in the 100-180 series. The 150 was the first PowerBook to use an IDE hard drive instead of the more costly SCSI drives found in previous PowerBooks.
