  • 14. How to select the right software
    • Match your hardware with software that meets your needs.
    • Stick with an OS that provides easy package management (installing/removing software).
    • Consider an OS that provides periodic updates.
    • Consider your upgrade path: how long will your software make your hardware viable.
  • 15. Selecting the right Operating System - Proprietary
    • Macrohard
    • That Fruit Company
    • If you have these OS es installed and they work, use them, however . . .
    • I don't advise purchasing the OSes listed above for older hardware for the following reasons:
    • Limited performance
    • Limited or no driver support for old hardware
    • Better value and performance with FOSS OSes
  • 16. Selecting the right Operating System – Open Source
    • UNIX – The Granddaddy of them All
    • PCBSD – a viable option (PBI)‏
    • Linux – The Big Three
    • Slackware - Austrumi*, Zenwalk, NimbleX*
    • Redhat - Fedora, CentOs
    • Debian – Ubuntu family*, Mepis*, Knoppix*, DSL*
