Admin: You are absolutely correct. Ereaders are not computers -- they are ebooks -- designed to allow someone to comfortably read any of the ebook formats to be found online (epub, pdf, lit, azf. txt and many more.) without eyestrain and the convenience and portability of a paper book. Like all electronic devices they come with all kinds of gimmicks and gadgets -- some good, some not so good.
As for the new e ink color -- not many people have heard of it because it doesn't work very well yet.
