Long Locks vs. Short Crops

It seems the stars are trading in their long wavy tresses for shorter do’s.  Being partial to my long hair, I always admire their bravery in cutting off the tresses and making a bold statement with a pixie or a bob.  I think we all remember the first (recent) celeb pixie with Emma Watson, but other leading ladies seem to be following suit.  What do you think?  Cut it off or leave it long?
