More then three years ago I blogged about "Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint File Formats" allowing users to open newer Word, Excel, and PowerPoint 2007 file-formats in older versions of office and received an DMCA take-down notice from Microsoft for directly linking to the file, I am not sure what pissed Microsoft off but one reason could be forcing users to upgrade when an alternative option is not known or easily available.
Thanks to Google Docs Viewer users can now view 12 new file-formats apart from existing PDF, Microsoft Word documents and PowerPoint presentations - the new supported formats are 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)and XML Paper Specification (.XPS).
