Windows XP users are kicking up a fuss over the eventual phasing out of their beloved operating system. Microsoft plans to pull XP from the shelves June 30, leaving only the Vista operating system, which has faced criticism from consumers and reviewers. XP users responded to the Microsoft's announcement with blog posts, petitions, and other online action. InfoWorld, a technology Webzine, has collected over 111,000 names so far on its “Save Windows XP” Web petition, which it started in January.
