Both e-readers and E Ink tablets use E Ink technology to render words and images on the page. They both offer a distraction-free experience that's easier on the eyes than a traditional LCD color screen. E-readers tend to be smaller than size and focus only on the experience of reading a book or PDF. E Ink tablets offer e-reading features but also include the ability to use a stylus to write notes in a digital notebook and/or in the margins of PDFs and ebooks. Since handwriting is integral to the E Ink tablet experience, the devices themselves tend to be bigger in order to more closely approximate the size of a sheet of paper.
