Bookeen, one of the first companies into the electronic reader market (1998) has released its fourth generation electronic book reader, named the CybookOpus.
Bookeen has tried really hard to keep up to the big players, Amazonkindle and Sony Reader. They've done a good job with the CybookOpus. It is slimmer, lighter and faster than many of its competitors packing a 400MHz processor into a compact 4 inch by 6 inch frame and a weight of only 5.3 oz (150 g).
