Linux is poised to take over the low-end PC market

Or so this article by Steven J. Vaughan-Nichols would have us believe:

I've heard this kind of thing said many times before (Linspire, anyone?) and it has never really come to pass. It's true that with Ubuntu and openSuse you don't have to know anything about Linux to use them for most basic tasks, but when you run into trouble you'll need to be able to find your way around Yast2 at least, if not the bowels of the Linux filesystem. I suppose that's the way it is with Windows, but I don't think that the average PC user is quite ready for Linux yet, even Ubuntu.
