Chapter 3. As discussed in the first article in this series (Switching to Linux: The Start), our first real task – after deciding to switch – is to make a list of software and functionality we really need. This should done carefully and with some reserve. The best way I have found is to work with your computer like you normally do for one week and keep a list of all programs you use and what you use them for.
The second part is to take a long, hard look at the list of software that are installed on your computer (Control Panel -> Add/Remove Programs in Windows). For each program you need to determine what it does and if you use it. If you really don’t know what an entry is for, then you probably don’t need it.
Next up you have to think about those things you do once a month or even once a year (like filling out your taxes). Do you need specific programs to accomplish these tasks? If so, do not forget to include them in your list.
