Hey, I have a MacBook Air from 2015 (1,6ghz with 8GBs of ram). I’m considering selling it and getting a second hand MacBook Pro 13 inch from 2015 instead, probably the base model or whatever I find. I already own a 27 inch 2017 iMac that I use for music production so I would use the MacBook mostly for university studies but getting the pro would maybe allow for some music production. So my question is, would the MacBook Pro 2015 last longer than my air and how much difference is the weight? Is it noticeable or just a bit heavier?
