Nope, all the cells are preformatted to be date (e.g. 2010-04-14). If I enter a date manually in this format (or some other format) it's OK, but if I enter a date using the slashes (e.g. 4/14/2010), then I can't change the formatting later. Doesn't matter what date format I choose, it won't change. I have to use Text to Columns wizard to be able (eventually) to change the formatting on the cell.
