I have gotten questions from several people who were at the Louisiana State Bar CLE last week about the differences between Acrobat Standard versus Acrobat Professional. In my mind, the biggest limitation of Standard is that you cannot do "Bates Numbering". See Rick Borstein's article about this @ http://blogs.adobe.com/acrolaw/2006/09/acrobat_8_new_f.html
What Adobe Standard DOES NOT CONTAIN: (http://www.adobe.com/products/acrobat/matrix.html)
