Want a highly customizable, performance driven, home screen replacement for Android 4.0 Ice Cream Sandwich? You can try Nova Launcher for free then. It is another nice ICS Launcher to replace default Samsung TW Launcher in Android 4.0.3 ICS Samsung Galaxy S II. And it is better than Trebuchet CM9 Launcher because root access is needed only when you want to use Widgets-in-drawer. All other Nova Launcher features and functions are workable without root access.
