I personally love quite a bit of the newish C++11 functionality, which is still not used by a lot of C++ developers I know, simply because they do not know of the existence of said features and because not all the features are supported by all the compilers.
Especially std::function, auto built-in smart-pointers are some of my new friends

I think a lot of features are just not known to many developers and the STL contains a huge load of stuff that comes in very handy quite often, but one has to know that it is there in the first place
