I've run Linux exclusively for the last 10 years or more both at home and on work machines. The last 6~7 of that have been various install of Gentoo. I'll admit that I run into issues every so often with a broken upgrade or some other little thing that I need, but overall, I've found that the machine just works when I need it too. Of course, I'm not looking to change things every time I turn around either. Once I have a configuration working smoothly, keeping it that way seems much easier on Linux than just about any other platform I've used, without the Apple walled garden.
