Beg, steal or borrow a Gmail account. Currently by invitation only, but probably due to launch soon - you get 1Gb storage and a great interface (it shows emails with snippets of content, like in a Google search). I've imported all my hotmail to it and it hasn't made a dent in the storage space. Ignore doom-mongers who claim it's an invasion of privacy (Google automatically targets adverts based on your email content)!
