Some of C++ features are great, as recently discussed on the Linux kernel mailing list. However for many of Cs usecases, they are not appropriate, like exceptions and RAII in embedded. Once you start disabling major features those 'power tools' become far less attractive. Also, to extend the metaphor, hand tools are usually obvious and easy to use while power tools can have very long manuals. See for example the 275 page book on just Initilisation in C++ [0].
