Who needs Windows?

Who needs Windows? Interesting article to read, and discussed in /. too. It would be nice to see that Windows-free world, however I doubt that would happen. Just like nobody needs in the end branded clothes, who cares for Adidas or Louis Vuitton - does that make Adidas or Louis Vuitton disappear? People still buy luxury clothes even though they know that there are alternatives. For computers - unless they have tried or at least searched for themselves, XP is just XP, and most people just don't consider anything else to start with.
