[TGS]

We have, and have had for a few hundred years, a name for those things with printed marks on paper (that, once bought one has the right to sell, give away blah blah...), we call them books and and so I'm not sure we need a new word for them. There doesn't really seem to be any need to capitalise or hyphenate the "e" in ebooks - given that there's no need to start calling printed paper books "Pbooks" or "p-books"or anything else other than books.

PS. What about those languages in which the equivalent of the English word "electronic" doesn't start with an "e" - Icelandic has "rafræn" and Filipino has "de koryente" (at least so Google Translate tells me).
