I got a new macbook pro and I just didnt like it.Didnt like the keyboard or the touchbar and I may be crazy but didnt seem that much faster than what I have now. So I felt it didnt warrant spending over 2k on. I like my early 2013 mpb much more. Here is the question, it runs great on mac os , still has great battery life. How many more years can I expect to get out of it or should I grab one of the 2015's still hanging around because its basically the same machine but newer?
