Why use StringBuffer?

Java's String class is pretty easy to use. I think it's a well-designed class.
I understand that String concatenation using + actually uses StringBuffer under the hood (so saith the J2SE 1.3 API spec). Other than that, what practical use is there for StringBuffer in real programs?

I believe that some code like this will be altered by the compiler:

and this is fine, since it's more efficient but happens under the covers so you don't have to worry about it.
If you're building a String in a loop, it can't be done so you have to use a StringBuffer
