Cybook Opus

The Cybook Opus is marketed as a pocket-sized ebook reader. It has a 5-inch (76 mm x 101 mm) E Ink screen, and weighs just 150 grams (5.3 ounces). It's designed to fit in either hand comfortably, and has a long battery life of about 8000 pages.

Its most unique feature is the G-sensor motion detector that automatically rotates the text when you rotate the device. The accelerometer quickly switches from one direction to another and is especially useful when reading PDFs.

You also have the option of turning the device completely upside down if you are left-handed, and when you do this the controls automatically switch too, so that page-forward is still the top button.

There are 12 different font sizes and a zooming options. You can change fonts in TXT and HTML files if you copy font files to the device, but you can't change EPUB fonts.

The Cybook Opus comes with a USB cable, black PU leather protective sleeve, and quick start guide. It comes installed with 100 French and English public domain ebooks. The 1 GB of internal memory is enough to hold close to 1000 books.

Along the bottom there are three keys: In the center is a 5-way navigational controller; to the left is the back button; and the menu button is on the right. The two long buttons on the side of the screen are page-forward and page-back buttons.

For organization, there are a number of options for customizing the view of the main menu. You can choose how many books to display, how to display them, how they're organized, etc.

It has a handy folder management system with sub-folders and customizable options. You can organize the folders onto a memory card and the order stays how you want it. There are a number of organizational options and ways to sort ebooks, such as file type, author, title, date, etc.
