Vanilla ROMs are great for those who are not huge fans of Samsung TouchWiz UI. Many, including me, find it slow and not that useful and thus, prefer having stock Android UI. Unfortunately, Samsung does not lets you uninstall it unless you flash a custom ROM like the one I have mentioned in this post.
An xda user at xda forums has released a Vanilla ROM for it. Features:
Based off of Vanilla Honeycomb (No Touchwiz 3.1)
