This is exactly what I wanted

a low cost, basic ebook reader.
I really want to have a reader for academic work but The publidhers and tech need to mature a little longer. So I still wanted a casual reader and this is it. I hope
Now for the milllion dollar question; How do I use it?
Actually I think it will workout. I plan to use Calibre. What format is best for the Jetbook lite?
