I think the eInk with light might both be manufactured by eInk, or whatever their company is called. If so then Amazon, which is the largest customer, should really pressure them to correct the manufacturing issues. Maybe Amazon should just buy them out and take over the process themselves. Kobo is a very small player so I doubt there is much they can do except complain. On the other hand, if Amazon puts the light layer on themselves then they need to correct the issues.
