PC World writes these kinds of articles, counting on the fact that readers won't take the time to research how much PC World hyped these very same technologies when they were first offered.
I love these list articles, and always read them, but what does it say about me, when I don't even know what the items on the list ARE?
Is it the same thing as when I read the lists of "Whose B-day it is Today?", and I don't even know anyone on the list except the 3 over 50?
