For teachers and students who want to work both at home and school, google docs is a great resource. It now supports all Office files types.
"The Google Docs Viewer is used by millions of people every day to quickly view PDFs, Microsoft Word documents and PowerPoint presentations online. Not only is viewing files in your browser far more secure than downloading and opening them locally, but it also saves time and doesn’t clutter up your hard-drive with unwanted files.
Today we’re excited to launch support for 12 new file types:
- Microsoft Excel (.XLS and .XLSX)
- Microsoft PowerPoint 2007 / 2010 (.PPTX)
- Apple Pages (.PAGES)
- Adobe Illustrator (.AI)
- Adobe Photoshop (.PSD)
- Autodesk AutoCad (.DXF)
- Scalable Vector Graphics (.SVG)
- PostScript (.EPS, .PS)
- TrueType (.TTF)
- XML Paper Specification (.XPS)
In Gmail, these types of attachments will now show a “View” link, and clicking on this link will bring up the Google Docs Viewer."
