Actually I think C++11 is a simpler language than C++03 or C++98. The problem is that we need to un-learn what we know and learn the new way of doing things.
C++11 is simpler for the casual user of classes but I'm not so sure it's easier if you're implementing a lot of classes yourself. I disable assignment and copying in all my classes by default unless I have a really good reason to implement them and I still pass by const & for types I define myself.
