"1em" is useful, although it is, as you rightly say, the default, because it allows the font size to be easily changed. If you set "1em" as the font size for something, and you later decide that you'd like it to be a little larger, it's easier to change "1em" to "1.2em" than to have to insert a new line into the CSS.
