One of my friends has used computers for many years and comes from a unix background. When he got a p/c with windows he just couldn't understand what all this different drives is about C hard drive A floppy etc. It just didn't make any sense to him.
My daughter who is 5 is much happier working with and finding her way round Linux Suse than with Windows XP. My wife who has been using Windows stuff for ages - struggles with Linux as she is used to the way Windows does things.
