End of an era -- no more hyphen in "email"

The Associated Press Stylebook, which rules like a god over its journalistic subjects, announced in March that the abbreviated term for “electronic mail” is losing its hyphen. So we are now supposed to write "email" instead of "e-mail."
This is a bigger deal than the change last year from "Web site" to "website."
This signals the end of an era, as one blogger put it, as we put aside a relic of a simpler time when Internet technology needed to be explained very carefully.
Snail mail is still to be written as two words. Is it time for a change there, too?
