Its not good. I love my kindle, but for textbooks it kind of sucks. Granted I have the smaller one. Formulae are ok from what I have seen, but graphs and charts are almost impossible to read. Also its annoying because often times a paragraph on one page will refer to a graph on the next page and switching back and forth is very tedious.
