I was wondering where to put this thought I had the other day, might as well be here...
What is Linux? Is it the mass market desktop of the future? Is it the ideal computing environment? Is it the best operating system that has ever been made or will ever be made? No. Linux was written so a guy could run Unix programs on his PC. That's what Linux is. I use it because there are some Unix tools that I use all the time, and even when Windows ports or Mac ports exist, they suck.
If you try and turn what is, when you get right down to the bare metal, an x86 Unix emulator (although it has grown well beyond that), into some kind of universal replacement, you will change things. This Linux that newbs are learning and Ubuntu is distributing and people here are fantasizing about is something else altogether. While that particular mystery OS might be enjoyable to use and perfectly fine, it won't really be Linux. It'll be something else. Because Linux, at its core, doesn't want to be the desktop panacea. It doesn't even want to be user friendly, and it would probably be served rather well by dumping all GUIs.
So I don't know how I feel about dragging things in that direction. I of course enjoy the GUI, I think it is convenient and pretty if nothing else. But if it was gone, I would still use Linux for certain *nix apps. At home I use OSX, and it is pretty much everything everyone here ever dreamed of. All Apple would have to do to satisfy everyone is make it free and open, and have multiple window managers to choose from. Nobody seems to be going in that direction with Linux - nor do they seem to even be interested in it. Which is probably best for the OS as a whole.
