Apple did have impressive build quality, but those days are long gone. I can run happily on a MBP from a few years ago, whereas the newer ones have had numerous issues.
In terms of overall quality, I'd say that MBP is now behind some of the other high-end devices. The Surface Book knocks the latest MBP versions out of the water in every department, except for the track pad. It's not difficult to argue that the keyboard, screen, durability, or even the OS is superior to Apple's (current) offering.
The biggest group that I've seen move away from the MBP range aren't developers, but are creatives - either in design or in sound/music. I know a few DJ's in my local area that have largely switched to Windows laptops because they feel tools like Ableton work better, and because they feel that for the price they're paying they're not getting value for money from the MBP range.
While it's nice to see an opinionated company like Apple admit fault and revert to what people want, I wonder if this move is too late for many of those that decided to move away from Apple?
Years ago, I switched to a Surface Book, and while I'm tempted to go back for this MBP I reckon that a Surface Book update would be enough to kill any desire for the Mac range. While Apple stagnated, many of the high-end manufacturers caught up.
This is the killer feature of GitHub for me. When learning a new language, being able to sense-check your code against what someone has done in the past has helped me understand how and why some things work the way they do.
