Hi, i can find a lot of comparison reports/pics/threads from 'MBP 2016 vs MBAir' to 'MBP 2016 13 vs 15' etc etc. But, surpringsingly, I cannot seem to find good pictures and hardware impressions from people who switched from the previous retina 15inch MBP (2012 - 2015) to a 15inch 2016 MBP. How noticeable is the difference in size and weight in everyday usage? Improvement in build quality? I'm switching from a Mid 2012 Base 15inch MBP to the higher 2016 15inch model. Any comparisons much appreciated!
