The one nice thing about enums is that you get two concepts in one column - a human readable label and a system used ordering. i.e., "SELECT enum_value FROM tbl ORDER BY enum_value" actually gives you a meaningful order without having to carry around, or relink to, a lookup table to get an ordering column. Now, this is a bit overrated since you immediately lose that ability if you export to a Spreadsheet program, or otherwise lose the ordering nature during a convert-to-text operation.
I do not suggest that ENUMS are useless just that there are more flexible and reasonable ways (as a whole) to do what ENUMS provide.
