The button is more or less ok and regardless i would totally recommend the Cybook it's a great machine.
I'm hoping that at some point they will release a software update so that I can attribute one of the other buttons as page turner (one of the ones on the left preferably!)
I'm not sure about anyone else but if i'm lying down i can't just hold the thing in one hand i have to use both when the page turn bit comes ..
not a huge thing tho even if i'm making it sound like a huge thing! lol ..
