My favorite, but no longer made, I think:

You might prefer the regular jetBook with a builtin battery:

It is the same hardware as the Aluratek Libre Pro.
Both have completed their software development and are very stable. As I mentioned I prefer the Lite with replaceable AA batteries and no audio.
The screen is not white like the Aura but has a high contrast that makes it very readable.
