I have not observed this issue.

Yes.

Converting the issue "back to articles"... if that means splitting up a single 
multipage PDF into constituent articles then there's nothing about A6 that improves on 
A5 in that specific regard.

Moreover... if you publish with "tail-ins" - ie, articles that start or end on the 
same page as another article starts or ends... no database tool is going to pull your 
PDFs apart!  But I figure you know that already.

It's not OS specific, but many Menu Items have changed between A4/5 and A6.  This 
means that using Menu Items for action-triggers using bookmarks, links and form-fields 
are not backwards-compatible.  For straight-forward PDF production without interactive 
features, however, this should not present a problem.

Another significant difference between A5 and A6 lies in the area of image 
compression.  In A6, JPEG2000 compression is available for color images... but it 
makes PDFs incompatible with A5 and earlier.

Similarly, in A5, JBIG2 compression is permitted.... but this makes PDFs incompatible 
with A4 and earlier (needless to say...).

Overall, and in the light of A6, I could not recommend to anyone that they "merely" 
upgrade to A5.

By the way, there is an excellent PlanetPDF Forum called "Acrobat 6.0" - it's all 
about this issue of A6 vs. A5.
