Maybe I have no place commenting, because I don't own a jetBook Lite. But I don't see any mention of the drawbacks that have held me back from buying it.
- no linking (not just me, I've seen owners wish for linking). I'm currently reading "The Book of Basketball," and it has literally several hundreds of footnotes that are all located at chapter ends. This book would be impossible to read properly on the jetBook.
Also, without linking, you can't simply skip past uninteresting Calibre newspaper and magazine stories.
- no support for public library (OverDrive) ebooks. Though hardly a knock on Ectaco, since they currently support one type of B&N DRM, and probably B&N ePub support is on the way, which is great DRM support for the price.
