Working Quietly. Ha not anymore.

Why would advanced technology such as the sharklets as mentioned not have been configured from the launch of the aircraft? Granted what is seen today was engineered ~4-6 years ago but regardless, the same could be said for sharklet technology. To me, cheapens the aircraft's original design. Just saying.
