My own opinion is that zero based indexing is generally much more useful, and makes a lot of things things simpler and/or more sensible mathematically or otherwise. However, there are some cases where an index based on some other number (often, but not necessarily, 1) is more useful. (Some programming languages, such as BASIC, allow you to define whatever starting index that you want to do.)
