    I also like to read on my likebook ( need bigger letters, so a 7.8" reader) and the backlight is great on the plane or reading at night,
    but I don't need that on the computer.

    But there are valid usecases for that, so if you need that, it's a problem.

    Does someone remember the old thinkpads with thinklight?

    Sure do! I think I have an old X220 sitting somewhere around the office with one.

    You can't have backlighting on e-ink displays since they are opaque.

    Good point, that's why the Kindle Paperwhite has 'frontlight' that comes in from the side. That would still be awesome to have on the Lenovo though.

    I do. I wish they'd stolen my suggestion: make it a 'blacklight' (near-UV LED) and put fluorescent paint on the keys. The keys would look like they're glowing, which would be a) a very cool look, and b) would likely allow for colors that are not that common, and c) would allow for simpler / cheaper / lighter keyboard. C'mon Lenovo, it's yours, take it!

    It certainly would, but it has diminishing returns. There is a reason makers don't put it on an Onyx Boox Max 2 or Sony on the DPR2 or whatever it is called.

    What's the reason? Maybe it doesn't scale well to large displays. I think it needs a somewhat thick transparent layer on the screen for the light to bounce around in. It might be that larger screens would require thicker glass/plastic. I honestly don't know. On the Kindle it works pretty great.

    That is the thing, around 8" the light doesn't reach far enough and that results in dark blotches in the middle of an e-ink screen. Not entirely sure but I believe it is a limitation in small LEDs. Hence the diminishing returns. But I'm also confident that engineers are working on solutions, but how far away they are is anyone's guess

    actually, the Onyx boox N96ML has a 9.7 inch screen with a nice frontlight.

    Yes, and I don't think there is any larger model with front lighting available. The Note is a 10" device and that is too big for lights.

    Well it's October now...which means we should see this beauty hitting the shelf soon. Looking forward to hearing some more hands-on reviews.
