I disagree, I think it would be useful if CCleaner incorporated clearing out the Apple installer cache. New versions of iTunes have been released at least once a month lately. Each time stuff gets stuck in the installer cache. Any cleanup task that goes stale that often would make an excellent addition, in my opinion.
And thanks for the link to additional information about iTunes bloat. Here's another -- an article regarding slimming down the installation of iTunes by removing some of the big components you probably didn't need in the first place.
Cheers!
