Sadly. It disappoints me so much that linux hasn't been able to crack Windows dominance on desktop/laptop. I was sure that as more people became computer "literate", they'd shift to linux or bsd in droves. Boy was I wrong.
It wouldn't have stopped Dell from creating a support assistant app for Linux to preload if they cared. In fact Linux being the land of NIH and non portability between distros basically requires Dell create a manager to sort out drivers and installs for everyone.
davidw asked the original question. I suspect his response was not to challenge the market share but to clarify why he asked. I don't think it's a non sequitur.
