In case you missed it, Adobe Systems recently released an updated version of its Acrobat document creation software. The company has said that Acrobat 8.1 is built to be fully compatible with Vista and all Office 2007 applications. "Both PDF as a file format and Acrobat as an application are now 'first class citizens' in these environments," said Acrobat developer Lori DeFurio.
Among other things, Acrobat will now be able to take advantage of a Windows Vista feature that allows users to preview documents without actually opening them, DeFurio said. Professional and standard editions of the software are available as a free download for existing Acrobat users. Acrobat 8.0 shipped in November, prior to the January debut of Windows Vista and Office 2007, and as a result is not fully compatible with the products.

Yes, however Vista HAD already been released to manufacturing by the time that Acrobat 8 shipped. Adobe's development teams have gotten increasingly slow over the years. Look how long it took them to ship a Universal Binary version of Creative Studio on the Mac! Then again, they did manage to get that shipped before Microsoft managed to ship a Universal version of Office.
This update from Adobe is very important, as they haven't touched the code in Acrobat 8 since September, long before the releases of Windows Vista and Office 2007..
For those that don't know who RyanVM is, what Autopatcher is to a fully installed XP machine, RyanVM is to a unattended installation.
Anbody who purchases Adobe Acrobat Standard or Professional only for the Microsoft Word plugin is insane. The program has so many capabilities beyond converting PDF to DOC and DOC to PDF.
As for the differences with the new version, maybe this will be helpful to someone... taken from http://www.adobe.com/go/kb401730 ...which has a detailed change log from 8.0 to 8.1.
