Rich Hintz's List: education

Can the kindle highlight text in multiple colors? No. Can it cross reference the questions in the back of the chapter with the answers in the chapter and not the page number of the related question near the question? Can it save that as a data file so students can share?  Can you annotate books with your own commentes, or corrections to the equation, or flaw in a theory? Can you notate what questions were in the test and may be worth another look for the final?  Hardcopy text books are hard to replace unless you are the kind who never needs them or uses them.
