Other than calling append(), you mean?  Maybe StringBuffer also cleared 
its buffer so it couldn't be reused (although I don't see that in the 
docs), however I'd bet that current implementations rely on JIT compiler 
to optimize away unneeded buffer copies.

I'm thinking this does mobile a disservice, however, because JIT might 
be hard to do on small devices.
