Why do you use Linux? I can think of a few reasons, but I'm sure people who've used Linux more than I have can tell me more. The reasons I've thought of: Linux is free. Windows costs money. Both of them let you do many of the same things. 'Sticking it to the man'. The man in this case being whoever is in charge of Microsoft these days, or just Microsoft as a whole. Bill Gates is focusing on his charity efforts these days I hear. Some people don't want to support big companies and this could be a reason to use Linux. I personally don't have a problem with them. As a backup. I personally have a bootable CD with some variety of Linux on. I've used it to return files before when Windows wouldn't boot for whatever reason. I also used it as a temporary OS while sorting out other problems, though I mostly used it to play MP3s.
