Time for U(NIX) 2 Retire
UNIX was a good operating system for its time. It performed well on relatively low-end minicomputers, and provided some of the features that had previously only been available on mainframes. For a PDP-11, it's an ideal choice. Modern operating systems based on the same philosophical design, however, are seriously hampered by compromises made to fit the system onto a machine less powerful than a modern pocket calculator.
