How can I edit Office documents on an Android tablet and keep compatibility? In our office, there's a new Eee Pad Transformer. It was supposed to replace a netbook for giving presentations and editing Microsoft Office documents on the go (e.g. Word, PowerPoint, Excel). 

There have been some issues:


The office solutions they currently tried can only read Microsoft Office files (like Documents To Go)
Polaris Office with write support produce Microsoft Office files that fail to open in Office 2007 Claim by the owner of the device, I can't try it.


The questions are:


Is there any way to produce PDF files from such documents? This would at least make it possible to just export presentations to PDF in order to share them.
Is there a (preferably free) office solution that guarantees compatibility with Office 2007/2010?
Any other workarounds?
I have MobiSystems OfficeSuite 5 for my Android (phone, not tablet though).  But I have never had any problems editing files, saving them and then opening them in Office 2007 &amp; 2010.  It does not have a save as PDF, but it does let you save in either .doc or .docx formats for word, xls &amp; xlsx for Excel, and .ppt &amp; pptx for Powerpoint
