So now you can uninstall all the third party applications/plug-ins that were used for playing flash movies embedded in PDF files.
Another major feature added to Acrobat Reader is the ability to integrated with Acrobat.com services. With action menu items available in Acrobat Reader now you can easily upload PDF documents to acrobat.com, share documents with others using acrobat.com, create new word documents online using acrobat.com and share your screen collaboratively with others.
Also the release notes of Acrobat Reader 9 says that it loads the PDF files much faster than the earlier versions. But I could not notice any improvement in speed when I opened few heavy documents with the new reader.
If not for the speed, Acrobat Reader 9 is worth upgrade for its for rich media support and seamless integration with acrobat.com services.
