There's a story over at Slashdot that points to an article written by Greg Raiz, a former Microsoft employee and user-interface designer. In it, he discusses what's wrong with Linux, and how Linux can catch up (and perhaps surpass) Windows. His points not only hit the nail on the head, they drive the nail into the board.
Unfortunately, but not surprisingly, a number of Linux fanatics are doing nothing but whine in the article's comments. This only illustrates Greg's point even further. Operating systems are no more than religion. You have your beliefs; I have mine. And just like with actual religion, it turns out to be rather difficult to convert people to your point of view.
