Everyday since 1988 or so.

IMHO, yes.  They were well worth it even when portable template
instantiation in shared libraries was well, shall we say, adventerous,

All the time.  Standard C++ has a fairly rich set of containers and more
importantly algorithms.

No way, iostreams are fantastic.  I have various classes that inherit from
iostreams for debugging, error logging, etc. and can print any object to
them that has defined that appropriate "ostream &operator << (ostream &,
const T &)" defined.  printf() and friends drives me nuts. Forget a format
specifier or get one wrong and the debug statement causes the program the
core.
