I got the game.  It's very enjoyable until you get to the point where it is too hard, then it simply becomes very frustrating.  ;)

I tried NiceFolders and once I figured out how to use it (despite what the web page says, it is not intuitive) it did exactly what I wanted.  :)

Honestly, other than being able to use more than 4GB of RAM, I can't think of any good reason to switch to Vista 64.  There's the whole 32-bit vs 64-bit program issue which has made several programs less useful under Vista 64 than they would be under Vista 32.  And I have had significant problems installing/running admittedly older games on Vista 64.
