The main difference between Vector and vector IMHO is the speed Smile

Since for Vector a=b just moves (pickes) the content, instead of copying it into the new container, it is way faster. In real life, most of the operations with containers doesn't care about the content of b after the operation. Sometimes it requires the programmer to think bit more about what he's doing, but the performance gain really pays off (See comparisons). I think I could count on my fingers how many times I had to use the deep copy operator <<=.
