Well, The new firmware has not fixed any of the issues with PDF's so that issue is still pending.
The battery life will probably take a few days to test properly.
As for the earlier comments, Personally I feel that while bookeen has been reasonably good in getting firmware revisions out, they have not been very good in testing them, and when releasing the fixes, not very clear about what they broke in the fixes along with what they fixed.
And not to mention, not testing out the older firmware on the new hardware. While it could be argued that they could not be expected to test old firmware on new hardware, it should be logical, when their standard response to problems is to roll back to older firmware, which does not work
