I look at Micro Center and see different specifications on 2015 ~ 2016 machines. 8 ~ 16 GB ram etc …
I don't know much about MB and don't know if an MBP is better than an MB if maybe MB you save some money and upgrade RAM.
I guess CPU and RAM are the most important things as most SSDs can be upgraded, but I don't know that either.
Q1. can you upgrade RAM on most MBPs?
Q2. are processor speed and RAM the big factors?
Q4. can you upgrade the SSD size, and if it has SSD + HD, can you upgrade both to larger / better SSDs?

The has i7 2.2 and 16GB ram. Then I see them more expensive with the i5 going slower? How is i5 compared to i7 on an MBP?
Example: 1/2 RAM, i5 and less storage for $ 150 more: https://www.microcenter.com/product/603629/macbook-pro-fpxq2ll -a-2017-133-laptop-PC-polished — space gray
