If the EE is really designed for the academic sector (students, faculty, and researchers), the major goal seems to be to eliminate the bulk of paper (books, note pages, and journal articles) while adding a little extra functionality. So, at least for me, I'd rather not have to tap on an icon to pull up a note, but, instead, I like the idea of scribbling all over my books/articles. Just my $0.02
