I fail to see how QVector in Qt4 is more usable std::vector. The only 
practical difference between them is that in Qt4, the 'size' method brokenly 
returns signed int ;-) I get an impression that in Qt4, interfaces of 
container classes became more similar to STL classes, so the question of 
which one to use is mostly issue of religion.

Qt signals provide dynamic binding (connecting to QObject knowing the *name* 
of the signal/slot, but not having access to the definition of the concrete 
class). Boost.Signals do not, so it's not exactly the same.
