So I bought a 2016 MBP 13" with touchbar a week before WWDC and so I am still in the return window. I love it and use it 5 hours on average a day. I use it for word processing, YouTube/Netflix, and coding. The only reason I don't want to exchange it is that as I said I use it every day and it would be tough living without it for about two weeks. The only two benefits I could see in exchanging it would be the minor battery increase as I do watch a lot of Youtube/Netflix and the future resale value. So should I exchange it or just wait for the 2018 MBP?
