Anything that makes re-installing your operating system easier is a good thing in my book. Ninite is a web-based tool that allows you to download and install your favourite apps with the absolute minimum of fuss. You select the applications you want and Ninite creates a custom installer which then runs with no further input necessary. The toolbars and other junk that some programs come with are de-selected by default and it’s free for personal use.
