ECTACO have showcased Jetbook+ on CES back in january and i've posted a hands on video. If you go to ectaco's facebook page you will see they are posting "teaser" pics of the JB+.. there is also the jetbook k-12 which is even more advanced. I'm not sure about the specs (and screen size) but ECTACO might start selling these later this year.
