Ghacks posted a story that Microsoft Office Starter 2010 is available as download from Microsoft's servers

Microsoft Office 2010 is available in different editions just like the Windows operating system. There is Microsoft Office Home and Student 2010 or Office Professional 2010 for instance. And there is at least one version that is only available to OEMs: Microsoft Office Starter 2010. This version is usually only available for users who purchase a computer system at manufacturers who add it as one of the installed software programs that the system ships with.

The particular version of Office ships with basic versions of Microsoft Word and Excel, the two most popular programs. It is basically free but comes with advertisement to make up for that.
