All I did was root my phone, not install a custom ROM. And I can easily remove the root if needed by reinstalling the OS. My reason to root was to remove the junk apps that came from the carrier (tone room deluxe, amazon apps, etc). I still have the stock ROM on it since it does the job.
I like my phone, but I didn't enjoy the stock apps, the theme, and the fact that Samsung JUST released a Gingerbread update. I've loaded custom ROMs to my phone, but just like you said I keep the stock version handy in case I have an issue. Wish all droids came rooted just to save the extra 2 minutes it takes to do so to get rid of those BS apps.
