5. Kingsoft Office (Free)
Main features: View, edit and create text and spreadsheet documents. You can view and edit slide-show presentations, but oddly, you cannot create one from scratch. View PDF files.
Cloud storage: Can load documents directly from your Box.net account for viewing and editing.
Microsoft Office compatibility: Loaded various .doc, .docx, .ppt and .pptx files we threw at it, but had trouble with Excel formats (.xls and .xlsx).
Conclusion: It’s disappointing that this suite can’t access your Google Docs files. Also, the spreadsheet app is really limited. But for a tablet, this suite has a cut-and-paste UI that works well, and is a decent reader app to view your Word and PowerPoint files.
