Be aware that most reviews of the Palma 1 are of the black version.
I have the white Palma 1. It uses a plastic screen, which was scratched very easily, so be sure to protect the screen if you get the white version. (The black version uses a glass screen that's apparently scratch resistant).
For a comparison between the two (white and black version), see this video:

My other complaint for reading was that the volume down button would often turn several pages on one press. This seems to be fixed in the upcoming firmware. I have used the beta version of it for a couple of days and have not experienced this bug on it.
