I will preface the following comments with the background information that I have an 8 year old daughter.
We were watching Disney's Hannah Montana show, one of Ryleigh's favorites I'm sorry to say, and the main characters mentioned an ebook. They were not reading the ebook, they were listening to an audio book on an iPod. The problem with calling the device an *ebook* is that it is misleading and ultimately incorrect. I am not saying that the Hannah Montana characters should be used as anything even remotely considered as an intellectual resource, but it does point out the ambiguity of the word.
