ok, i have only registered to give my opinion.
if i was a doctor and you came to me saying your arm hurts, i wouldn't just say "No it doesn't" and thats basically what all the people who think that this isn't annoying are saying .
i'm actually going back to XP after this and i just wanted to say that this is just retartedly bad. if YOU don't customly arrange your folders then that obviously means that you don't need to, but for the people organising hundreds of folders, they just may need to once or twice move some folders to the most appropriate position that suits them.
I myself do this hundred of times without thinking twice about it, if this is taken away from me then it just makes everything that little bit harder.
