What I was going at - but failed to mention - is what happens if you have an array that's larger than your largest block of contiguous memory? Using a vector, it's possible to store that, having it broken into chunks scattered wherever there's space, as opposed to simply going "Hrm, we need to add elements, okay, let's go find a new chunk of free memory that's current+50 bytes."
That's what happens when I don't completely explain myself
