Hi guys. I just recived my new macbook pro with touch and i use him for the last few days.. He is little bit heavy for me so i think to replace him for the 12 macbook 2017 I just want to know the main difference between these 2 . I use the mac for office, browsing (about 7 pages), win 10 with paralles (very light use) , watch movies and youtube. Can you please advise me what to take? Also, can you tell me wich one of them have more chance to get an update soon?
