If we can find quarterly sales data for dedicated ebook readers that goes from 2002 up to present, that would be a good start. The model I used was rather limited, it was missing many factors in it, which we might be able to improve by finding
1.) Quarterly info on the new ebook reading devices released.
2.) Quarterly info on the ebook reading devices sold.
I imagine those two variables are linked strongly to ebook sales, so it would be great to find such info. I just don't know how feasible it would be, since companies don't like to give away their sales info unless it makes good press, and it would have to be trackable each quarter of a year from 2002 to 2009.
