The PowerBook 1400c stands out in Mac history as the first Mac laptop to include an internal CD-ROM drive (6X speed, if you must know), an incredible feat of miniaturization for any laptop at the time. This new internal optical drive brought portable Macs a new world of software and the flexibility to easily access large collections of data on the go. The 1400c shipped with a PowerPC 603e processor, first introduced in the PowerBook 5300 the year before. (Photo: Apple, Inc.)
