I am studying Korean from koreanclass101.com by printing out sheets. I am sick of carrying paper and would like an ebook reader which can read the Korean fonts from the koreanclass101.com worksheets. I tend to scribble on paper which allows me to highlight text so that I can ask people questions about grammar later. Is there an electronic ebook reader which can allow me to do this? If so, which one is good? ideally the software should be easy to use and in Engish.
