15" 2012 Macbook Pro Retina. Bought it a little over two years ago used from a pawn shop (more accurately: an Amazon seller that I later discovered was a pawn shop). I use it for hobbyist coding (Ruby, Javascript, HTML, CSS) and browsing the internet. Runs nicely even on the newest OS update, Mojave. For general tasks, It is noticeably slower (but only slightly) than my desktop (which is 5 years old), but the performance is great for being 6+ years old. Even runs simple games well. Really like the keyboard and trackpad. This is the first and only laptop I've ever purchased; I've always gotten by with desktops both personally and at work.
On the desktop side I always go Windows. Price is king for me. I'd never buy a Macbook new. My next laptop will be... something work gives me and I just won't bother buying another. I don't really need one. Maybe I'd grab another laptop if I decide to stop buying desktops, which may happen, as I'm trying to cut back heavily on videogames.
I do not like the scissor keys on the newer Mac laptops, which would greatly discourage me getting another. Maybe my next laptop would be another used Mac, but the most recent model that has the older, better keyboard keys.
