Not gonna happen. Distro is short for distribution. Linux is open source, and any Tom, Dick or Linus can distribute his own version.
For example, if Linux came out with one desktop home version, they might effectively challenge MS’s Windows Home.
[...]Linux is working against itself by continuing the multitude of flavors.
There is no "it," and there will never be a One True Linux. That's part of the whole open-source idea, which is the main reason Linux is free. But if one Linux distro could package its OS with a pretty interface and an easy install "wizard," then seal it in shrink wrap and bundle it with off-the-shelf PCs, you'd have something like what you describe.
The problem is, it's been tried, and it didn't cut into Windows' market share much at the consumer level. Never mind that Linux will handle the same documents, connect to the same servers, and browse the same Web sites as Windows, a lot of folks want to run the same binaries as all their friends.
It was bad enough 20 years ago, when we had PC DOS or MS DOS or OS/2, GEM Desktop or Windows Desktop, WordPerfect or Word or Wordstar.
Yeah, it really sucked when there was competition. Isn't a monopoly much tidier?
I just don’t want to spend the time to learn Linux and determine the differences to find one version that best suits may usage.
If you don't take the time to become an informed consumer, then you get whatever crap is easiest to buy. That's true with everything you buy.
