Hello I am wondering... I own a rMBP mid-2012 base model and I don't know if I want to upgrade to a newer model. Is still a good laptop in 2016? I work in Logic Pro sometimes and I want to know if I can use this model for the next 2-3 years without any problems. I wanted to exchange it with a dual core mid-2014 model but I lose the performance and the screen . What do you guys think? Are you happy with 2012-2013 rMBP models ?
