What is the difference between Adobe Reader 8.1.3 and 9.2? When I go to the Adobe Reader download page I may choose one or the other. It says 9.2 includes on Adobe AIR, but I don't know what that means.

Why would I choose 8.1.3 over 9.2?

That's about it... Other than that - whatever newer features are in the latest version of Adobe will be supported... All I can quickly find is:

* Submit Adobe PDF forms that are created with fillable form fields in such applications as Adobe Acrobat Professional and Adobe Form Designer
* Play back a variety of embedded multimedia content, such as QuickTime and MP3 files
* Read and organize high-fidelity eBooks
* Activate search and accessibility capabilities built into your PDF files
* Display Adobe Photoshop? Album slide shows and electronic cards and export images for online photo processing (online photo services vary regionally)

Also, as Nick points out in the comments, also general security updates.

Hopefully security improvements, Adobe Acrobat and Flash products continue to be exploitable components. – Nick Josevski Nov 11 '09 at 23:18
@Nick +1! of course - I will add to my answer. – William Hilsum Nov 11 '09 at 23:57
Why would Adobe still offer version 8? – M. Dudley Nov 13 '09 at 3:30
It may be that the newest version does not support an operating system or configuration that a previous version does. – William Hilsum Nov 13 '09 at 5:48
