I've had my accounts since 1999 when I signed up for Freeserve dial-up.
The great thing that is unmatched by other free accounts is that you can put anything you like before the @ which is invaluable for tracing where spammers obtained your email and for inbox filtering and killfiling.
Also invaluable when email address is required for a login, because you can have multiple variants for multiple accounts, it's this that I am going to miss most.
I suppose I should be thankful that the service has been available for as long as it has.
