Bookeen Cybook Opus E-Readers


Extremely lightweight, intuitively designed ; ePub support ensures plenty of content ; Lots of font sizes

A bit pricey ; Lacks extras such as dictionary and annotation

Review: Bookeen Cybook Opus e-book reader


If you've been waiting for a no-frills e-book reader that's scarcely heavier than an iPhone, check out the Cybook Opus from Bookeen.

EPub support ensures plenty of content ; Extremely lightweight ; Intuitively designed ; Lots of font sizes

Lacks extras such as dictionary and annotation

The navigational wheel and the select button it surrounds guide you through context-sensitive menus that pop up when you press a button to the right of the wheel (a Back button sits to the left of the wheel). The menus have a fairly simple design; you...

Bookeen Cybook Opus eReader


Consumers either loved or hated the navigation on the e-Ink Bookeen Cybook Opus eReader — but if size is a major pain point for you this is a great pick because it’s small and super light-weight. By supporting both industry standard formats,...

Cybook Opus review


The wafer-thin Opus has arrived to take on the Kindle and Sony Reader Touch. But has it priced itself out of the competition?

Compact, skinny and light – except in the price department

Cybook Opus


The Opus is a decent bare-bones reader; but for the same price, the Sony Reader Pocket Edition is a much better proposition.

Fast boot-up and loading times ; Super lightweight ; Easily fits into a bag or large pocket ; microSD ; Comes with protective slipcase ; Go To page function ; Bookmarking

Screen quality poor ; Sort functions have a learning curve ; No PDF reflow ; No dictionary ; Navigation fiddly ; Plastic chassis and buttons prone to unattractive scratching

The Cybook Opus is available in Australia from eReadersRus.

Bookeen Cybook Opus review


Available in an array of colours, and weighing just 150g and measuring less than 1cm thick, the Bookeen Cybook Opus wrests the e-reader portability crown from the Sony Reader Pocket Edition; unfortunately, its £199 price tag is a bit larger.

The Bookeen Cybook Opus has pretty much everything you need to read a lot of books, in a very small and lightweight package. But you won't find extras such as a music player, the ability to create notes, or text-to-speech support . And though the Sony...

Bookeen Cybook Opus review


A simple ereader with support for open formats, the Opus is light, easy to use and stylish, and our only concern is that it's too expensive.

Bookeen Cybook Opus


Bookeen's latest iteration of its Cybook Opus puts a little spit and polish on the original, which was one of the skinniest and lightest e-readers available. At 150g, the new Cybook Opus retains the featherweight crown, but the  €167.22 price ...

Sleek and snappy-performing e-reader; light weight makes for easy one-handed operation

No music player or dictionary; pricey; no Wi-Fi; must hook up to PC to get content; no integrated bookstore

Like the previous version, the revised Bookeen Cybook Opus lacks some of the frills you get from less-expensive e-readers. It has no support for wireless content downloads, and no built-in music player. And although the Opus ships with a ...

Bookeen - Cybook Opus


Ereaders are, apparently, going to be one of the hit technologies of 2010. There are certainly more to choose from today than there were a year ago, and in the UK you can even buy them ...

With no really fancy features, and a small and pocket-friendly design, the Cybook Opus is one of the best ereaders we have seen.
