Me too, but perhaps cheap AMOLEDs will come sooner and they can kind of be an okeyish replacement? If one runs an AMOLED on black background, e.g. a terminal, a text editor or an inverted PDF, only the pixels displaying characters will be lit.
Maybe this is good enough? I experimented with an AMOLED tablet displaying inverted PDFs and it felt similar to a Kindle. However, this was my completely subjective perception. It could be that in the long run, it is tiring for the eyes as well. IMHO, the worst part about displays is staring at a bright LED backlight all day long. Screens such as Dell UltraSharp, which are able to dim the backlight a lot and do not flicker feel much better.
Sharp's Memory LCD comes pretty close. It's a high contrast LCD with a reflective back layer that mimics paper and has very low power consumption. But I believe it's only available on small sizes, and it's a one-bit display (no greyscale).
This screen is used in Panic's Playdate game console as well as the Pebble smartwatch.
