It's all about 'good enough'..
Lots of people seems to have jumped on the usual 'bash Windows Linux is great' bandwagon.
For almost everyone, Windows is GOOD ENOUGH. Linux for most is not good enough because it involves hassle, or even just the concept of hassle for most people.
Take the iPhone. Although the hardware is gorgeous I think the software is awful. But for the vast majority of people it is GOOD ENOUGH.
In the case of the article, the technologies are not good enough to be taken up en masse or not good enough to stay. For technologies that are supposed to be dying but defy the test of time, they are good enough to do the job (for now).
