I have the high end 15 inch 2017 right now but love the 13inch size. Would it be a huge downgrade getting the 2018 13inch with 16gb ram? I use it for office work, internet, etc. No gaming, video editing, etc. I have a desktop for more power... After selling my 15 inch and getting the 13inch, I'll probably take a slight loss, but just wondering if its a big downgrade considering the 2017 15inch has dedicated graphics, etc. Thanks.
