Cybook Opus is a 5 inch e-Reader, specially designed for reading e-Books and e-News. It is produced by the French company Bookeen.
Description
The Cybook Opus[1] is an ultra-light reading device based on E Ink screen technology. It has a foot print of 4.2″ x 6″ x 0.4″ inches and weighs 5.3 oz (150g), battery included. It features E Ink electronic ink with a 200 dpi display which is enough for text, although not enough for high quality images. Its screen possesses a paper-like high contrast appearance and is readable under direct sunlight. Actually the contrast increases in bright light. It isn't the best E-Ink screen available, as it supports only 4 shades of gray compared with the 8 or 16 shades on some other readers.
Controls
The control system include: -two long buttons to the right of the screen (in standard portrait mode) to handle page navigation. Side buttons can be flipped (“Advanced…” menu), allowing one hand page turns with thumb on lower button (portrait modes only). -a four-way navigation wheel with a button at its centre below the screen, which is primarily used for navigating the menu system but can also be used for page navigation. The menu is activated by a dedicated button, and then there's a back button to return to the previous option or screen. It has an accelerometer that allows it to switch from portrait to landscape mode automatically (if the option is enabled), which will appeal equally to left and right-handed readers. All the controls change to match the orientation, and always behave as you'd expect - whichever page button is "top" or "right" will go to the next page, and the "bottom" or "left" button will go to the previous page, no matter which way around you hold the Opus. While reading and also in the “Library”, keeping next/prev. page button pressed will enter ultra-fast pagination mode.
Battery and power
It has a Lithium Polymer (Li-Polymer) recheargable (and replaceable, unlike other devices) battery, with a battery lifetime of 8,000 page flips. The page flips are the only thing that consumes battery. To charge the device, you use the same included USB cable that you use for transferring content to it (either via free Adobe Digital Editions software or by dragging and dropping to storage). It takes 5 hours for a full charge. It has been reported by some users that the battery meter is not very reliable since the 2.1 firmware update.
Storage, copying and organizing the library
To a host computer the Cybook functions as a typical USB mass storage device. You can categorize your books into folders and subfolders for easy access. It allows for virtually infinite menus. File “Delete” option. You can easily copy books from most computers without the need for special drivers. It is supported on all major operating systems, including Linux. It stores up to 1 000 titles in 1GB of built in flash memory. A Micro Secure Digital card slot allows for expanded storage, which does support SDHC cards for up to 32GB more storage space. Having a memory card slot means you can share the Opus with family members and simply swap out the card containing your library for theirs.
Formats supported
The device uses TrueType fonts (TTF), and can also be used as an image viewer. Text formats : Adobe ePub / PDF (native or DRM-protected), TXT FictionBook (.fb2) and HTML files without any conversions. One has to choose between ePub or Mobi (due to Amazon contract restrictions), but you can swap Mobi and ePUB firmwares as often as you wish (and as sensible). Conversions from all formats can be done with 3rd party software such as Calibre. Image formats (black and white): JPEG, GIF and PNG 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.
Fonts and text display
12 font sizes, from very small to very large (works with ePub, HTML, FB2, TXT).You can add your own fonts. Create a folder called "Fonts" (the name is case sensitive) under the "CyBook" USB drive and add your TrueType or OpenType fonts to it (works with ePub, HTML, FB2, TXT). Layout can be switched between justified and left-aligned text (works with ePub, HTML, FB2, TXT). Text emboldening: allows setting text in bold for maximized contrast (works with ePub, HTML, FB2, TXT).
Language support
User interface is available in a total of 23 languages: Czech, Danish, German, Greek, English, Spanish, Finnish, French, Croatian, Hungarian, Italian, Dutch, Norwegian, Polish, Portuguese, Romanian, Russian, Swedish, Turkish, Slovak, Slovenian, Chinese simplified & Chinese traditional. Note: to be able to select a Chinese user interface, a Chinese font must be present in the “Fonts” directory. Support for Chinese, Japanese & Korean (CJK) file names and metadata. Non Latin/Greek/Cyrillic text will automatically be rendered using another user supplied font (“Fonts” directory). It works for all left-to-right languages. Accepts any text encoding. It has automated character set recognition for HTML, FB2 & TXT files (works with Latin, Cyrillic, Greek, Chinese, Japanese & Korean).
Operating system and firmware
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. June 2010 Bookeen published a much improved firmware[2]. This new firmware, (V2.1 build 1198) brings the 1 second mode: Cybook can be switched on/off in 1 second, keeping last read page open -this allows you to switch on and off without having to boot each time.

Pros and cons of its features
As it lacks a keyboard, it does not have dictionary support, annotations and bookmarks. It also does not have wifi internet access, text-to-speech support nor the possibility of listening to music while reading. It is meant only for reading, like a physical book. The main concern was to make it small and lightweight, so that one can read for hours without discomfort. It uses open formats and standards so it won't lock you into one company's products in future.
