Office 2010 Web Apps and SharePoint 2010

So it work with SharePoint but what does it offer:

1. Create, View and Edit Excel, Word and PowerPoint documents (BUT only Office 2007 and 2010 documents – docx, pptx, xlsx)
2. View and edit Word documents
3. Co-author Excel files (really! two people editing the same file at the same time and see each other’s changes as they are made!)
4. View PowerPoints, with transitions, fades, etc! In the browser or as a full screen slide show.
