The good point with the odyssey, folder view, hyphenation (for ePub).
Downside (sometime an advantage), the screen is not as white. Rather large default margins so books usually needs editing. I like the fact the kobo can (at least for kpub), set margins.
There is a new odyssey version that cames out a few days ago. (Better usb port fixing and on/off button change). So if you get an odyssey, make sure it's a new version.
