Well, I have the new firmware, but couldn't find a list of changes or bugfixes.
The scribbling seems unchanged (with some minor issues), as mentioned by myself in the other thread:

I can't comment yet on the random hiccups and hangups when reading epub or pdf files.
The IR sensor is still unreliable.
The handwriting recognition is a joke, but I'm not sure that feature would be useful in any case. The note-taking (Notes) is therefore a waste because the pen-typing is awkwardly slow and sometimes unreliable, and the handwriting recognition is crap.
I still can't export pdf annotations (sketches/notes), which would be a major feature.
Lots of things to do for the firmware guys. They'd be better off opening the device for open-source soft-/firmware.
But: if it works, the reading is just great on the device. No matter if epub/pdf or anything else that's displayed.
