An anonymous reader says "A friend of mine recently switched to using Windows XP after three and a half years of Linux. I thought the community might benefit from reading his story. Even as a dedicated Linux user, I agree with many of his points. 'Unix on the desktop" has come along way in recent years, yet could still stand much improvement. It is no longer an issue of having a fancy GUI (KDE can't get much better), but rather the real problems lie in the foundation.'
Some of his points are wrong, but it's a reasonable article.
