We have already commented here on the site a few times about the latest update of MacBooks Pro with Retina display. Speaking specifically of the 15-inch (top-of-the-line) model, little has changed just an increase of 0.2GHz in the machine's processor.
Because Americanas.com is selling the MacBook Pro from the end of 2013 (that is, the penultimate generation) for R $ 8,639.28 cash (bank transfer or bank transfer). J the new model sold by Apple for R $ 13,139.10 view.
Taking into account that there is practically no difference between them, the savings of practically R $ 4,500 can be a good one for those who want to change machines.
