Can you tell me more about your favorite item that you like to buy. Im not too familiar with Color E Ink.
Amazon came out with the first eink devices with their Kindle devices which are strictly black and white. I've heard that color eink is coming out.. I've heard 
Oh wow that is super interesting to learn. How do you enjoy reading E-books vs the new Color E-Ink Device? I hear they are more healthier.
Yes. eInk devices are much easier on the eyes.  They are not backlit, so aren't blasting blue light into your eyes.
Yes i was just reading how it is much easier on the eyes. That would definitely be great to have for reading. 
Yes.  I have an older Kindle and have been looking to upgrade. Makes sense to get a color device if I can find one. Have you seen any out there?
No i have not. But now that you mentioned it. I want to see when these are coming out. I think like you mentioned it would be better for the eyes.
I think the color devices are available in China, just not sure what I can find in the States.
Ahhh yes that would make sense now. Well hopefully soon they will be available to us.
Have you heard of any technology similar to eink that might be just as easy on the eyes?
