Hi, I am trying to decide between the 2016 macbook pro non touch bar 2.0ghz base model vs the 2015 macbook pro 2.7ghz base model. The newer macbook has the better screen, future proof connections, thinner and lighter, bigger trackpad but the 2015 has the easy connections for daily life, £300 cheaper, magsafe, SD card slot. My normal useage for a computer is word processing, internet use, video watching, photo editing/lightroom. Battery life is important to me i need as much as possible also i cant be dealing with any lag in my day to day tasks especially programs like lightroom with big files. realistically i will be plugging in the charger, iphone, sd card, 4k external monitor, external hard drive. Which one do you guys recommend as the better purchase?
