I think that it does make a difference more & more, especially aol, yahoo, hotmail and some of the other free ones. I work in the world of publishing, specifically classified advertising, and we have a huge amount of fraud attempted with these types of email addresses. Even gmail is beginning to be suspect. I understand that everyone wants an email address that is portable. A service like MobileMe costs less than $10 a month and it's portable and offers other advantages as well.

You'll never get more women anyway. There's very little to shop for; and women don't want to learn anything; they think they already know it all. :)
