What I like about my Mac is that it brings the unix programming environment I need together with a nice and clean user interface. My MBA is super light, I can take it anywhere without hassle, and apart from some age showing (such as “30% is 0% now”) the battery also lasts quite long. I’m also a big fan of the built-in Terminal emulator, it’s lightweight, speedy, and has the features I need (tabs, colour scheme support (any love for gruvbox?)).
That said, this might be personal, but I have not been a fan of the recent MacBooks at all (ports, touch bar, all the stuff around the keyboard…), might just be a personal thing. I’m glad my old macbook is still working as well as it did on the first day
