I have to take back that I'm entirely happy with PR1.2. As I posted here, the standard (osso) PDF viewer seems no longer capable of displaying mathematical formulae, which for me is a real letdown.

Fortunately, the pdf readers in Easy Debian are intact! If I only could have them open automatically from microB!

EDIT: I've filed a bug report on this issue: https://bugs.maemo.org/show_bug.cgi?id=10345
Consider voting for it, if you share my frustration.

EDIT2: Rather off-topic by now, but in case somebody else here wants to have the standard pdf viewer fixed quickly: Replacing just the one executable /usr/bin/osso_pdfviewer.launch by the version from PR1.1.1 is enough. (Always do backups! )
