iTunes is not so bad. Quicktime is the worse piece.

Quicktime installs as a plugin in every browser and you can't get it out until you unistall it. Even if you delete the plugin DLL's (for example in firefox) they instantly replace. You will always be forced to use the quicktime player when you want to download a sound file. You can't just download a sound file anymore, you have to wait until quicktime finishes loading it and then save it from it's menu. Some times you even can't save, it just doesn't let you.
