      Which to me is a far better solution than that of many who would discard high-level features that are a real benefit to a few, for the excuse that you can do the same thing with a little extra thinking and a little extra work.

What makes Linux such a difficult platform for folks that are new to it is that Linux exists only in our minds, and actually manifests itself as 1000 different distributions, each just different enough from each other to cause problems with interoperability. Combine this with the vast amount of customization within each distribution (including lots of variables, like IF something is installed in the first place, and then looking at library versions, desktop environments and program versions to determine how everything will inter-relate) Because we (Linux users) have complete choice in this manner, there are no "easy" answers when we seek help, because those helping us are not working with a system that is in a known state. In fact, most users probably don't know what state their machine is in.

      Contrast this with Apple or Windows, and you'll see why troubleshooting is so much harder under Linux. This, by the way, is the exact same phenomenon you see in PC gaming versus console gaming. Bugs are very easy to reproduce on consoles, because everyone is running the exact same platform (or very close). On a PC, there are 1000 different variations in hardware and software configurations that could cause a bug.

If your personality craves "just work"-itude, then play games on consoles and use Windows or OS X (please choose OS X).
