- Windows - Available on the DPO/EIE machines. Such machines are
often "dual-boot", meaning that they can run Windows or Linux.
- Linux - Linux is a version of
Unix. It's (nearly) free. Unix has been around a
long time, but it hasn't always looked
nice. Now there are several versions of Unix that have such a comprehensive
graphical interface that most users don't need to use the command-line.
MacOS is perhaps the best known.
