I've never understood the thing about taking notes myself (mind you I never did any higher education); what is the lecture explaining that isn't in the textbook? The textbook should be all the notes and information you need, maybe supplemented with online; not keeping notes will allow you to focus on the lecture itself, which should be an extra on top of the book.
The actual act of taking the information and processing it into your own words, and then also the act of actually writing those words down, has been shown to improve memory retention and understanding of that information over what you would get from simply reading the same information in a textbook.
