These portable personal computers integrate a disc-reading mechanism, allowing users to access and utilize data stored on compact discs. This capability facilitates software installation, media playback, and data retrieval from physical media. For example, individuals can install legacy software or access archived data without requiring an internet connection or external drive.
The inclusion of this optical drive offered a significant advantage in terms of software distribution, data storage, and media consumption. Before widespread high-speed internet and USB drives, it was the primary method for installing operating systems, applications, and accessing large files like music and videos. It supported offline accessibility and data archiving.
