I prefer ebooks for reasons others already stated, including:

• can carry a huge collection of books in a single portable device, such as one’s phone
• can customize the text’s formatting
• can customize ereader’s appearance
• can easily save quotes

I wanted to highlight accessibility, which is most important to me. I struggle to focus while reading, and listening to a screen reader narrate a digital text while looking at the written words helps me push through. With use of a screen reader comes the ability to adjust the speed, pitch and/or voice for faster or slower reading, and it’s extremely useful when there are no existing audiobooks for said material. The consistency of a synthesized voice allows me to increase the speed and still understand, while audiobooks will contain pauses and emphases at the discretion of the narrator.

In some cases, ebooks can be shared more easily with people who are not physically nearby. I also frequently use full-text search for specific terms.
