Why have anything. Just save your money and die with it all in your mattress. Life is suppose to be fun. We all spend money on stuff that people think is stupid. If there was not marketing we would all be on single speed bikes with coaster brakes. Sometimes there is no good justification for buying something except that it makes you feel better.
My money is waitng for Campagnolo's electric shifting. Why, because I want to. Good enough reason for me and I could careless what you you all think.
