Echoing this sentiment, got a precision 5520 pre-loaded with Ubuntu and it's been a real champ. The build-quality is on-par with Apple and the fact that I still have HDMI/USB-A has been a life-saver a whole bunch of times.
There's one other thing that I like too; it's linux.
If I bought a macbook I'd definitely leave OSX on it, OSX is a decent system but the lack of decent window manager, the fact that I can't navigate with just a keyboard and the fact that I don't have the ability to mount linux-y/windows-y filesystems except fat is an annoyance too. But they're not annoying enough to make a good Mac Laptop a half-decent linux laptop.
