The Cybook Opus is an ultra-light reading device based on E Ink screen technology. Its screen possesses a paper-like high contrast appearance and is readable under direct sunlight. The device offers a battery lifetime of 8,000 page flips. The Cybook reads many file formats and offers access to a wide range of digital documents. To a host computer the Cybook functions as a typical USB mass storage device, which allows for easily copying books from most computers without the need for special drivers. For this reason it is supported on all major operating systems, including Linux.
The device uses TrueType fonts (TTF), and can also be used as an image viewer to display JPEG, GIF and PNG files. The Cybook technically supports PDF files, however it doesn’t actually reflow text. Current firmware revisions support ten levels of zoom and allow scrolling around the page, making the device suitable for reading many PDF files. A Micro Secure Digital card slot allows for expanded storage, which does support SDHC cards.
The Cybook Opus runs Linux as its underlying operating system; however, the firmware is open source but not the application. This could be due to the support for DRM protected e-books, which probably require third party libraries.
