Summary: Currently, I have all three sitting in front of me. The K3 is the biggest and heaviest, although not by much. After all, the K3 has a 6" screen with a keyboard, whereas both the Opus and PRS-350 have a 5" display and no keyboard. The K3 offers G3 connectivity in addition to USB, whereas the PRS-350 and Opus only have USB. So, as a Kindle owner, you can buy books anywhere in the world where a G3 connection works.
Summary: We had a heck of a time figuring out how this E-book reader works. We followed the directions closely and still had problems. We also had a problem with the USB Icon super-imposed on the screen of the E-book while trying to read a book. Quite odd. We are going to send our E-book back and try another one, possuibly the touch screen Sony. This Bookeen was tough to understand and use.
Decent bare-bones reader but hope you don't ever need aftermarket support

Summary: Bookeen has been around much longer than the Kindle and for a long time, it was one of the only readers that could be purchased in non-US countries so it has developed a rather loyal following in international circles. However, Bookeen has squandered a great deal of their customer loyalty by introducing buggy software and promising firmware fixes that, if delivered, are often more than a YEAR later than announced.
Excerpt: Possiedo questo prodotto da diversi anni e ho letto circa un centinaio di libri in questo modo. Adoro il concetto di lettore di ebook e credo che ne avrò sempre uno da qui alla morte. Purtroppo il BCO non si è rivelato un grande acquisto per tutta una serie di problemi. I principali sono stati una grande tendenza al freeze e la necessità di frequenti reset, soprattutto in seguito a spegnimento completo; una lentezza mostruosa nel navigare le cartelle ...
Pros: tutto sommato, funziona, e quando lo comprai il prezzo era buono rispetto ad altri prodotti .
Cons: molto lento, soggetto a freeze continui, poco pratico da usare se non durante la fase di lettura
