If you’ve been waiting, the color version of the Cybook Opus is now upon you. The device will come in seven new colors with a May 7 release date. The freshly updated Cybook Opus features instant-on functionality, a new Boo Reader software to help optimize battery life, and 12 font sizes.

It’s still a monochrome E Ink display at 800 x 600 pixels and memory is still 1GB, but the price has gone down to £149 ($199 in USA). 150 books come preloaded on the device, so that price is pretty awesome.

We first told you about Bookeen’s Cybus ebook reader back in may. Then it was briefly spotted in July. After that nothing. So we figured they gave up on their expensive e-book with no Wi-Fi.

Well, it’s back and now shipping. For the price, at least it looks different than other readers. The E-ink ebook reader weighs just 5.3oz and features a 5″ display, 12 font sizes, 4-level greyscale and 200 dpi and the built in accelerometer lets you auto change from portrait to landscape mode.

Bookeen was apparently showing off their pocket ebook reader, the Cybook Opus, and those who have seen it sound pretty pleased. The ebook reader has a display of 200dpi with 600 x 800 resolution and auto-rotation.

It supports file formats like ePUB and PDF, DRM or no. It comes with 1GB of internal storage that can be expanded via the microSD memory card slot. The large page-turn buttons on the side make sense, and it supports up to a dozen font sizes.

Here’s an e-book reader that does things that the Kindle 2 won’t. Like fit in your pocket and have built in PDF support. The reader weighs in at just 5.3 ounces and packs a nice resolution of 200 DPI. Some other features include a 6″ display, 1GB of flash memory that can accommodate ePub, PDF, HTML and text formats. You’ll also have access to a catalog of 150,000 books.

Software features would let users pick one of 12 font sizes for readability as well as let owners organize e-books by folders. Battery life will give you about 8,000 page flips, which is quite a few novels(Or one Robert Jordan Wheel Of Time novel.) No 3G wireless feature, but you’ll get 21 days at standby.

Bookeen is set to drop on the world a new e-book reader which uses new e-paper technology from E Ink. The Cybook Gen3 will debut in the United States this September in several different packs starting at $350.

The Cybook Gen3 offers up a rich and clear 6-inch screen in a body form factor which Bookeen describes is the size of a paperback, the thickness of a magazine and a weight of around 6.1 ounces. The e-book reader has USB connectivity and a battery life which offers around 8,000 page flips.
