The endowment will help close this digital divide.
It will promote both ebooks and the best hardware to read them on and even pay for ebook friendly hardware in some cases—for example, helping out poorer library districts.
Revving up production of dedicated ebook readers, a benefit of increased demand, can only help drive down prices.
Meanwhile other book-capable devices such as tablets and cell phones will only get cheaper in the long run. On top of everything else, ebooks cost less to store and distribute—no small factor in the case of rural libraries with limited budgets.
Of course, knowledge, not hardware, is often the issue–maybe even the main one. The endowment will promote the cause of ebook literacy.
