@mtripoli: you bring up some good points! How ever, it looks we missed a major point about this, the article quotes "Triton achieves color by adding subpixels with color filters above them..."
It turns out the attenuation of light due to filtering can be as much as 60% which makes these types of displays unattractive for eBook reading.
There is a Silicon Valley company, SiPix, that makes dual mode displays using ePaper that eliminates this problem without using the colour filters.
In any event, the printed electronics industry (ePapers included) are targeting high volume consumer applications including text books for K-12 and college. Not having good colour display capabilities is a serious limitation for that market.

With the new color tablets and readers on or soon coming to the market, I think this was a very good competitive move and the timing is right. The benefits of E-ink are recognized, but many (including myself) have felt the the B&W was lacking in usability. Should be a real plus for the eReader market.
After the introduction of the iPad, E-Ink redoubled its efforts to bring out color--fast. My guess is that we will see color eReader early in 2011, with perhaps an announcement or two as soon as Christmas!
There are a few things that get "over looked" when talking about e-ink and it's implementation. The first that comes to mind (for those without Kindles or Nooks); you can't display "graphics" with it. If you, like so many others got any kind of "ebook" that contained graphics in the text, it doesn't display. Try looking at a book about Da Vinci without graphics. Secondly, it's not back-lit (or side lit or any other "lit"). You have to have an external light dangling over the "page" in your face. Sorry, that's not progress. You can argue that LCD's wash out in direct sunlight, but honestly, how many times have you ever really felt the need to bring an electronic device with you to the beach (if you are, you're going to to the beach for the wrong reason). If the "color e-ink" is anything like the existing stuff ("flash black before going white" everytime you turn a page) then we'll be seeing all sorts of colors everytime you turn the page. I'll take a proper LCD...
This e-paper technology is certainly promising and appealing. Someday it will surely replace the paper if this e-paper is made flexible and fold-able like an ordinary newspaper. If not physically then the MEMS support can be used to design e-paper where pages can be turned back and forth by the users thumb action
There is definitely a place for this new color e-ink paper, but I wonder if the lack of video speed and color depth capability will tip the e-reader market more to iPad like devices. For outdoor use, the e-ink solution has proven to be very acceptable and popular. But for older people who may be more home bound, I'm thinking the more vibrant colors of an iPad type device makes reading books as well as magazines, etc easier for them. I am aware of the many pro/con arguments about various forms of e-readers, but for these type of people, I don't believe the downsides of an iPad type device would be particularly harmful compared to the better experience received.
This is fantastic news. E-paper is ideal for any display other than video and for such applications, consumes way much less power than other display technologies. E-book readers no doubt will seek this technology.
