I don't use snow leopard, still on a powerpc at my work. They are using CS3, I suggested they may as well skio CS4 now and save their pennies for new intel hardware cos CS5 will also be intel-only.
I've found a few things about leopard fucking annoying though.
A couple include the stupidly small character count displayed on filenames on icons on the desktop. Not sure if it's always been that crap and this workplace just uses really long names for everything or leopard is different from tiger. I eventually found out how to alter it in terminal.
Another is that search, no matter where you are or what folder you are in, defaults to the entire computer. (worked in tiger, and fixed in snow apparently)
Then there is one of those mac-logic things of putting deleted items on removable drives to a hidden trash folder so there is still no room on the drive until you empty the trash, which, and this is the bastard, you can't empty separately from the desktop trash.
Oh and last is the complete inability to merge folders. You need to find a sync utility, and quite often I find them a bit confusing.
This has nothing to do with what you asked, but I saw my opportunity
