I had the 2015 13" MBP for about two weeks, the keyboard looked flawless when I returned it to purchase the 2016 15" MBP. Having it now for three days, the keyboard looks like it's getting some oil spots on certain keys. I've also noticed oil spots in reviews of the 2016 MBP on YouTube...so before I use my new beauty, I always make sure my hands are good and washed/dry. My hands are also not oily kind of hands. Is anyone noticing the new keyboard is perhaps more finger oil prone than the previous keyboard version?
