Thirty thousand people have now signed InfoWorld's "Save XP" petition, which was launched a week ago. Roughly half were from the U.S. and the rest from other countries.

The petition asks Microsoft not to discontinue Windows XP as planned on June 30, but to instead keep it available alongside the newer Windows Vista indefinitely.

More than 100 people have added their own comments to InfoWorld's Save XP blog, and many external sites have promoted the campaign by adding InfoWorld's (a sister publication of PC World) countdown clock to their sites. The vast majority of comments supported the petition drive, providing a variety of reasons that both individuals and companies do not want to lose the option to obtain new XP licenses available after June 30. Lack of compelling benefits in Vista, coupled with the training, support, and other costs of upgrading was the most cited reason. Some cited compatibility concerns.

Some commenters thought the campaign was silly, arguing that change is a fact of life in technology and that there's no sense in sticking with older technology. This argument drew retorts that change for its own sake was not a worthwhile approach.

In an interview, Burton Group executive strategist Ken Anderson suggested that the strong emotional support shown in the comments indicated a fundamental shift in how people, including IT staff, now think of operating systems. They have become a familiar extension of what we do and how we work, thus not something want to change often. "When technology becomes part of you, you don't want people to mess with it," he said.

Anderson likened the reaction to XP's impending demise to what happened in the 1980s when Coca-Cola replaced its classic Coke soda formula with New Coke, causing massive protests and forcing the company to bring back the now-rechristened Coke Classic. "XP has come to the point of being Coke Classic," he said.
