I would expect it to be as proportionally thin as the bezels on the current lighted Kindle, Kobo and BN readers.
Personally, I think portable devices are more portable when the horizontal width is kept as short as possible, even if that means making a device taller or thicker. The wider a device is, the more unwieldy I find it to be.
