I have a Jetbook. After a month of agonizing efforts I have to conclude it will not properly display the public domain books at
http://books.google.com/bkshp?hl=en&tab=wp
It was suggested in the Jetbook forum that no reader will display these books.
The reason being they are scanned document and not text.
So the question.
Are you successfully reading books from this site? No funny pages? No shut downs?
If yes, what reader are you using?
