As a graphic designer, I used to be 100% windows -- and even somewhat against the hype of apple products. A friend had an old 2008 macbook pro collecting dust. I figured I'd try out OSX for a time, purely in an effort to fix her laptop. I fell in love with it and picked up the 2013 a few months later.
As time goes on, I don't doubt that we'll see the 2015 maintain its resale value.
You won’t regret Surface, fantastic hardware and W10 is not nearly as bad as the haters say, esp. with WSL now. I’m a switcher from MBP myself and I am very happy with the decision.
My MBP is luckily the last decent one (MBP 2015) and it has 16 GB DDR3 and 256 GB SSD. However it does have an Intel GPU, and only 2,2 GHz quad core i7.
Since I'm on 400 cycles at about 5% battery loss and a few minor but annoying damages on the screen I'm gonna get the latter repaired. Problem is I'm not sure how they got there in the first place. So I'm not sure how to prevent it. And the time to get such fixed is withering away. Tick tock, 2015 was 3 years ago.
