Re: Adobe Flash auto-update status

I wouldn't worry as much about Adobe's lack of PPC support as I would with Apple's.

We're a month or so away from Mac OS X 10.7 (Lion) being released.  If history
is any indicator, 10.5 will quietly cease to get Apple security updates in short
order.

An important caveat: the latest versions of Flash simply aren't available/
aren't supported AT ALL for PowerPC architecture Macs. Thus, if you go to 
http://get.adobe.com/flashplayer/otherversions/ and select 
Macintosh OS X 10.4-10.6, and then attempt to "Select a version" your
only option will be "Flash Player 10.3 for Mac OS X 10.4 - 10.6 (Intel)"
(note the "Intel" there, although, of course, most users won't). 

This lack of support for PowerPC Macs is confirmed at 
http://www.adobe.com/products/flashplayer/systemreqs/

This same issue also exists for the latest versions of Adobe Reader 
(e.g., Adobe Reader X (10.1)). See
http://www.adobe.com/products/reader/tech-specs.html

This is a problem for two reasons:

-- Users may get conflicting messages about updating, and they may waste
   time attempting to upgrade (when in face their platform has been 
   orphaned by Adobe)

-- Those hosts that will be forever unable to run current/patched 
   versions of these important apps represent security vulnerabilities 
   on campus just waiting to be 0wn3d.

If the current versions of the applications are vulnerable, and won't
be patched, I'd hope that Adobe would at least flag this condition and
recommend that users knowingly and intentionally uninstall their products.

Allowing users to continue running perpetually unpatched and unpatchable
products is just nutz (IMO).
