Gmail, Yahoo, Yahoo.co.uk, Lycos, HotMail, mail.com, spymac... so many free web-based e-mail services. Of course, being free, there are compromises to be had.
Among all the free web-based e-mail services you've encountered, which would you rank in your top 3 (highly recommended) list? Conversely, which would you rate as the absolute worst (highly recommended -- to your enemies)?
Please qualify your responses (based on speed, reliability, storage space, interface, ease of use, extra features, etc.).
p.s. I think we can include Edsamail.
