Pro The pre-installed OS that it comes with is developer-friendly
OSX is based on XNU (Darwin) kernel, it's certified Unix and arguably a lot more developer friendly than Windows. Development for Unix is native on OS X.
There's a large selection of great development tools available for OSX. 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 OSX and iOS software, for free.
Pro Fantastic display
13" MBP has a sharp, color accurate 2560 x 1600 IPS display. It's bright at 286 nits, has great viewing angles (viewable at up to 178 degrees) and capable of displaying 87.3% of sRGB color gamut.
Pro Very light and thin
The 13" MBP is just 0.71 inches thin and 4.49 pounds light.
Pro Good battery life
The battery drains in about 9 hours of typical use.
Pro Great performance
The combination of a 4th gen i5 and an 5200 integrated GPU makes for a powerful laptop.
Pro Sturdy construction and elegant design
The MBP has an all-aluminum body that looks great and is sturdy enough that worries of accidentally damaging are mostly alleviated. It has a robust lid, well-spaced back-lit keyboard with speakers on each side of the keyboard and an excellent button-less trackpad.
Pro Good stability

Con Requires the use of proprietary firmware
The source code of the firmware isn't available for users to audit or modify.
Con RAM is soldered in
A crippling, unmitigated rip-off which prevents you from upgrading the internal RAM.
Con Glossy screen
Apple has deleted the matte-screen option from its lineup, an unfortunate decision that reduces the usability of the computers and means you get less work done. You won't realize how much time you spend moving your head around to get reflections off whatever you're trying to see until you switch to a matte screen.
Those "deep blacks" and "rich colors" that you were supposed to get from a glossy screen are not present, since they're buried behind a sheen of reflection under all lighting conditions.
Con No Ethernet or FireWire ports
An adapter is required to transfer data over FireWire or connect to the Internet using an Ethernet cable.
Con Computer is glued together internally
The battery and other components are glued in, and the battery blocks access to other parts. The battery will wear out eventually, and the fact that it's glued in means that Apple prevents you from easily repairing or upgrading a MacBook Pro.
Con May have problems running Windows or Linux
For users who don't want to run OSX, it may be hard to find drivers for that work with Linux or Windows.
Con The default OS spies on you
Apple spies on its users, and helps others spy on them too. OSX needs to be wiped from the laptop and be replaced with Linux or another acceptable OS before it can be used.
There have also been cases of security issues being reported and not fixed for quite some time. An example is a security issue in iTunes which was left unfixed for three years while it was being used by the government to collect data. These security issues may or may not be intentional, but other data collection is.
Con Comes with macOS
Comes with macOS, which is quite crippled for an advanced user who wants to tinker and have the latest tools. For a newbie macOS is ok, but to do simple things that advanced users want to do, like installing certain packages you have to install stuff like homebrew and other hackish third party extensions. Try mounting an linux file system from it.
Con SD Card sticks out
The SD card slot does not allow the SD card to fit in flush, making for an unsightly item sticking out of the beautiful casing.
