Launched ten months after the original PowerBook 1xx machines, the PowerBook 145 was the direct replacement for the PowerBook 140, and was later re-badged as the PowerBook 145B.

History

The launch of the original three PowerBook 1xx machines had certainly proved that Apple could make a decent portable Mac and, by simultaneously launching three different machines aimed at three different markets, they could be forgiven for resting on their laurels. Nevertheless, sitting still in the I.T. industry is never an option and, just ten months after it was launched, the PowerBook 140 was the first machine to get an overhaul in the form of the PowerBook 145.

From a technical perspective, the 145 offered very little over the old 140. Even from an aesthetic and user perspective the 145 offered very little over its predecessor. In fact, the 145 was little more than a 140 with a slight speed bump (jumping from 16 MHz to 25 MHz) and a slightly bigger hard drive: 40-80 MiB rather than 20-40 MiB. Hardly much for buyers to get excited about – except for the price drop of $800.

While the move from the 140 to the 145 increased speed and hard disk capacity, the change from the 145 to the 145B didn't even offer that. In the ten months between releasing the 145 and the 145B, Apple didn't exactly push the limits of technology, instead opting to just drop the bundled microphone and install disks, bump up the onboard RAM, and reduce the price to a ridiculous $1300.
