"...which duplicate much of the C++11 functionality." In all fairness to Qt, the original version of the library predates the ISO approval of C++11 by 16 years! Much of the functionality the library provides was not even close to being available in the c++ standard libraries for many of the years since it was first released. I understand if Qt is not your cup of tea, but many successful applications have been written with it, and a lot of that is due to the breadth of functionality the library provides (and in a cross-platform way). It's a tool like anything else, and I don't think it deserves to be dismissed out-of-hand.
