There's no limit to what you can do with Linux. Its Open Source nature means you're free to modify it in any way you want in order to make it work for you. There is often no need for such involved customization: PowerPack will let you turn your computer into an advanced workstation without any effort. Here are a few examples of advanced uses of PowerPack.
PowerPack as a workstation for Intranet/Internet development
Open Source technology has turned into the standard for Web development. You can set up PowerPack for those in no time - it is all pre-configured. Quanta or Emacs will prove excellent IDE's for editing HTML, XML or PHP code. PowerPack's network and development features will be invaluable.
PowerPack as a Scientific Workstation
Many research scientists are Linux users - with reason. All major software applications used by researchers are available under, and very often are mainly targeted for, Linux. PowerPack includes SciLab (a Matlab-like environment) and Octave for scientific computing. R is one of the most extensive environments for statistical computing available. LaTeX is used by thousands of scientists for typesetting journal articles in a clean, logical way. Dozens of more specialized packages are also available. PowerPack provides an outstanding environment for research.
