That would help a lot I'd think. An issue with e-ink is it's black on gray, so the contrast has to be really good to get good readability.
With a white background it wouldn't be so crucial I'd think. Or if you can invert it and have white text on black back ground. But of course I'd have to see it and read on it to know.
In any case, I'm interested in seeing what all these new screen techs can do. I think were still a handful of years away from having these new screens excel at reading and video etc. My next gadget will likely be something with an LCD screen with LED lighting like the iPad while I wait for the technology to mature on these new types of screens, since readability isn't my main concern.

I don't think any reflective technology gives close to "true" white. EWD like Liquavista expects to get above 50% white reflectance (some claims state 60%), EPD like E-Ink stands around 40% (SiPix's flexible-backed MicroCup stuff mentioned 33% reflectance). Some technologies like electrofluidic and electrochromic are [at least theoretically] capable of above 80% (pretty white). For what it's worth, Mirasol's white papers suggest they are capable of around 50% white reflectance, compared to 60% for the Wall Street Journal (print version, obviously). Bear in mind that white reflectance can be measured in different ways, so the numbers are not always completely comparable.
White reflectance will certainly improve overall readability in diverse light conditions, but black reflectance is also important to consider. Without a solid black state, even good white reflectance will look washed out.
