Rather than buying kindles/nooks or new e-readers, why not use existing technology that is already in learners' hands? Take a look at the use of cellbooks/ mobile novels in South Africa - which have been used in education, and particularly in reaching school children who otherwise do not have access to printed books (but do have cellphones). Some wonderful pioneering work done by Steve Vosloo of Shuttleworth Foundation, who released a cellbook with good take-up in September last year.

It dramatically reduces costs because you don't have to buy e-readers, but more importantly, it uses a technology (mobile phone) that learners are already comfortable with and therefore skills transfer is easier.
