Set Per-Folder Views in the Finder
Tired of navigating to a particular folder and having to switch to List View every time? With Finder in Leopard, you can set viewing preference for each individual folder. Just navigate to it, and set the view the way you want (Column, List, Icon, or Cover Flow). Then choose View > Show View Options (Command-J) and in the window that appears, select the Always Open In... checkbox.

On a happy note, this update finally fixed a small issue I was having with my P1006 (where photos would print as if somehow magically down-sampled to 32 or 24 colors). Huzzah.
For simpler, third-party apps, I just make an archive of the current app and any prefs (although that file seldom changes) BEFORE installing the update. If things "go south" all I have to do is delete the new file and un-archive the old on. It's usually much, much more difficult to to use this method for SU stuff, files could be being updated all over the OS... ;-)
