Typical cases for the One Button Installer
Tool that is easy to use and just works
The normal linux installers that come with iso files are complicated to use or freeze during the installation process, and you want a tool that is easier to use and just works.
Replace Windows XP
Replace Windows XP because you want the computer to work faster or smoother with an Ubuntu based linux operating system, or at the end of life in April 2014, when there will be no more security updates for Windows XP.
You want a simple method to backup (and restore) your whole installed linux system. The One Button Installer combines installation, backup and restore in one set of tools.
Your own portable Ubuntu based linux system
You want to make your own linux system portable and port it to a USB pendrive or to be installed in another computer to be used by yourself, or to be uploaded to the internet for sharing with other people. The One Button Installer can do it in a simpler way than to remaster the code and make an own iso file.
