Version 1.2 of Student Pad is available on AppStore here Student Pad for iPad on the iTunes App Store It's cool!
Excerpt from developer's blog:
"So what is new in this version 1.2? We have finally finished the functionality that iPad uses are waiting for so long: ability to highlight and sketch directly on the PDF books. Being inspired by a comment on NYTimes 2 months ago, we believe that our solution perfectly fit what is missed in the market right now: "I think the publishers undervalue a student's desire to highlight and otherwise markup his or her textbook. If I could take notes in the margins on my e-textbook and flip *very* quickly through pages, sections and chapters, then I would likely ditch hard textbooks for good, especially those outside my major and ones I don't think I'll ever reference again in the future."
Personally, this is also what we have experienced at schools. Reading books, especially financial, academic or reference books are not like reading novels: users need the capability to highlight important ideas, markup a chart on the book, or write down some main points which come out of his mind while reading. I bet you won't like the feeling that you've just forgot a *million dollar idea* while reading a book several days ago, just because you had nothing to note it down at that time, right? And not only books. Think about lecture notes or slides: taking notes during lectures give you an advantage during the exams
Aside from highlighting or sketching directly on your book, if you are a tidy person, you can use the built-in post-it note available on every page, which you can type, draw or doodle. It's fun, isn't it?"
