Actually my choice to use hotmail is a reflection of me X years ago when I created the account. It is also a reflection of the state of free web based providers X years ago. You don't know the value of X, which makes it difficult to draw any conclusions from my email address.
I guess it's also a reflection of the current me in that I don't see the point of going through the hassle of ditching an email address just to have something slightly more trendy (and slightly more usable).
