Pro Amazing display
Everything about the display is very good - from its high resolution (2304x1440) to the brightness (325 nitts), uniform brightness distribution (90%), and high contrast ratio (1000:1) with over 95% of the sRGB spectrum. Overall, a great display which will come in handy for people who work with visual arts.
Pro Decent battery life
The battery lasts around 7h30m of continuous web browsing which is about average for this class of laptops. Where this laptop's battery truly shines though is under heavy stress where it manages to last an impressive 2h35m under a total stress test (maxed out brightness and processor usage - circumstances that you are likely never going to encounter in the real world).
Pro macOS is developer-friendly
macOS is based on XNU (Darwin) kernel, it's a certified Unix and arguably a lot more developer friendly than Windows. Development for Unix is native on macOS.
There's a large selection of great development tools available for macOS. The operating system itself comes bundled with a powerful terminal emulator, called Terminal. Additionally, Apple provides tools, like Xcode, an IDE that contains a comprehensive collection of tools for developing macOS and iOS software, for free.
You can also install Homebrew, an extremely useful package manager.
Pro Excellent trackpad
The MacBook has a large 4.4 x 2.7-inch Force Touch trackpad with a Taptic Engine that delivers haptic feedback whenever the user taps on it to give them the impression that they are actually clicking on it. It also supports gestures and multi-finger swiping.
The accuracy is almost perfect and there's virtually no lag or stutter when using the trackpad.
Con It's a bit hard to get used to the keyboard
The keys are pretty shallow, with a travel length of just 0.5mm. They still provide good feedback and the writing experience itself is not bad, but it's just a bit hard getting used to, especially if you are coming from a laptop that's not a MacBook.
