So the processor is rebranded but pretty much the same. SSD is faster but will you notice it with light duty work? You can get more RAM if you want which again doesn't quite match the purpose of the MacBook - light duty. The keyboard is upgraded. Is the keyboard really the best update for it? I'm thinking about getting one for the wife to replace her aging 2011 13" pro. Just not sure if the 2017 is worth the extra money vs. the m5 512 2016 model.
