I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used.
However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers.
The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux.
Anyway, I am now looking at moving to a Mac in the hope of finding a stable GUI and a feature-packed command line.
Does Mac OS have an integrated command line where I can do linux-like-awesomeness like
wget, crong jobs, package updates, and
git without having an unstable GUI?
Basically, until the linux GUI applications get a little better, is OS X what I need?
