One question : do you happen to know what the changelog is for 3.4.0 ? It is probably worth switching, no ?
Taken from the Document Foundation blog:
"LibreOffice 3.4.0 offers several new features for Calc, with faster performances and an improved compatibility with Excel spreadsheets, and Pivot Table – the new name of DataPilot – with support for unlimited numbers of fields and named range as data source. The user interface of Writer, Impress and Draw has been improved with many new features, and several cosmetic changes have been applied to the Linux version, with a better text rendering engine and an improved GTK+ theme integration. Code wise, several thousand lines of German comments have been translated into English, and over 5.000 lines of dead code have been removed from Writer, Calc and Impress."
