I was looking for an Office application for the tablet. With Documents To Go I first sometimes found an app in German. Created with Microsoft Office xls and doc documents are opened easily and can also be edited. Recommended as a free app for now. So far, there were no annoying commercials, which indeed would be in a free app basically necessary. Whether now opposite the BezahlApp missing some features which I do not know. When BezahlApp is also impossible to tell whether the German language can be selected.
