Email or e-mail?

Marking the end of an era, Wired News has changed its house style from “email” to “e-mail.” The decision to change is explained with great detail, and care, by Tony Long, copy chief at Wired News. While I will likely keep spelling email sans-hyphen, I understand Long’s reasoning (grammatical history, ease of editing). For me, however, e-mail (with a hyphen) will always look a bit clunky.
