Color e-ink on the way - Boing Boing
Like the title says.
So, e-ink is the kind of display used in the Kindle. Portable devices that show color are LCDs that are awful pretty, but have battery life issues.
This is something new. And you will end up reading your comics on it, sooner or later. I recall something like five years or a touch more from "first e-ink reports" to "second-generation e-ink platform". Likely longer, but in the great scheme of things, not that long.
