well, for most Indonesian kids, “digital” seems to be closely related to “gadget”, which is apparently closely related to “games and similar stuff”. monochromatic gadget like kindle (the old edition) will work just fine here, i assume.
From the KQED.com article:
Mark Pennington’s students often read on their laptops. Pennington, who’s a reading specialist in Elk Grove near Sacramento, Calif., sees a need to teach kids how to read digitally and stay engaged, and thinks that digital reading will eventually catch up to what kids can do reading print. When asked if his seventh-graders are more engaged when reading from digital readers or in print, he said it depends — motivation and environment play a big role.
