You posted pictures some time ago proving that M92 has Cool Reader running on it.
Does the same is true with Firefly?
Does Firefly have Cool Reader?
It is important to me to have at least 1 cm margins on each side in landscape orientation on 6" device so Cool Reader ensures that. Otherwise - who knows.
As to this front edge light technology.
I have two concerns about it:
1. Because of the light distributing film layer the contrast is worse compared to the same screen without the light. So when the light is turned off it is worse than the corresponding model without the light.
2. Sooner or later, cracks develop (or scratches are made) in that light distributing layer (judging from multiple reports about Nook ST Lightglow) - and then bright light spots appear in the middle of the screen when the light is on. So the light can no longer be used, but the contrast is still lost because of the presence of that layer.
Could that layer be perhaps removed, peeled off, when so happens
