SMA, with ICS you can disable most of the bloatware apps, which is basically the same as you would do rooted. If you're rooted you freeze the apps which is no different than disabling. But you wouldn't want to delete them (even though you could rooted) because if you needed to go back to stock to take an OTA update or to return your phone you wouldn't be able to without the deleted apps.
To disable your apps, go into app manager in settings, along the top scroll to all apps, find the apps you don't want then uninstall or disable. Some apps you have to uninstall the updates before you are able to disable them. If you ever need to re-enable them, they will be listed at the bottom of the all apps list.
Hope this helps.
