If you're happy with how your iPod is currently, then doesn't that deem this thread pointless?
You said yourself you're happy how it is.
Imo, there is no need to upgrade to 1.1.3, all you get is a few bug fixes, a metal dock and lyrics support. Also in 1.1.2 you get calendar add/edit support, but there is a tweak in installer.app to add that.
