Hi All, Wouldn't it be cool if you could be able to highlight (yellow marker like) sentences of a book on the iPad, since Apple is trying to push these iPads into the schools to replace textbooks, I remember that for me was easier to highlight important parts of a book for when I had to study for exams later on. This of course ruined the textbook, but of course for me was useful. So if I could highlight the electronic version of a textbook and then close the book and reopen it, and having it still highlighted would be a cool feature, and of course you could undo any marking you did, or even delete all the markings, in case you're giving the E-Book to someone else. I think you get the idea of what I mean, do you think the current Book app will support this? or is there any app on the iPhone that does this? Thanks.
