There have been books around as long as I can remember, we were already reading and writing when we got to kindergarten... in 3rd got into an argument with the 4th grade teacher over whether I could check out a 6th grade book...and then whether I could return it.
Basically we will try anything that holds still long enough to read it.
With a good cross-dictionary and time, have even tried to read foreign books...without much success.
At this point in time, the only way we can read an ebook is on the computer itself in pdf or rtf format.
