The Macintosh is the most user-friendly computer. Windows is trying to
achieve the friendliness of the Mac. UNIX is the richest, most popular
software development environment, and is becoming a universally accepted
standard for distributed computing. It has an abundant set of communications
protocols and file sharing software - Telnet, r-series, email, file
transfer, NFS client and server. MachTen makes that plentiful environment
available on a Macintosh.
The combination of Macintosh and UNIX has been enthusiastically embraced by
both Macintosh and UNIX lovers.
