Touch Wiz

Is this app essential to the operation of my phone? what will I be unable to do if I disable it?

It is a part of the OS so it is essential, however you could (root and) use another ROM and do away with it if you want to make that move.

Thanks. No root for me so I guess I'm stuck with it.
