Today, I returned my Open Book reader to Walgreens. I wanted to hold out for more firmware updates, but I doubt if they will come along. Instead they make just come out with an updated model. I remember Foxit did something similar with the Eslick. Then the new updates would not work for the first models. After many complaints and months later they finally came up with an update for the first devices. Who knows. If the reader ever gets itself together, then I will certainly buy one again. It's sad. I have never returned an ereader before.
I reallly would like a dedicated 5" color reader.
I have a Chinese PMP that uses a Rockchip. It is made by Onda. I don't know if it is the same thing.
