I've used C++ since 1997.

Don't care much for the STL. Its syntax is nice, and I don't mind the size overhead much, but the compilation time is noticeably increased the more templates you use.

C++11 has a bunch of syntax improvements, like "auto" and inline class member initialization. I think I'll use it for most of my future programs.

Probably, yes. But it will be hard to make sure it's done right.
