PC Pro reviewed the iRiver Story. And to no one's surprise, it's not a bad eBook/PDF reader, but it's too expensive compared to more established competitors.
While PC Pro praises the use of ePub format (it's not tied so closely to one store like the Kindle), they put its build and display quality below the Kindle. They say it's a lot like the Sony Reader PRS-505...but far more expensive for no justifiable reason. (The Story costs the equivalent of $US380.) [PC Pro via Engadget]
