For them, the impending disappearance of XP computers from retailers, and the phased withdrawal of technical support in coming years, is causing a minor panic.
Take, for instance, Galen Gruman. A longtime technology journalist, Gruman is more accustomed to writing about trends than starting them.
But after talking to Windows users for months, he realized his distaste for Vista and strong attachment to XP were widespread.
"It sort of hit us that, wait a minute, XP will be gone as of June 30. What are we going to do?" he said. "If no one does something, it's going to be gone."
So Gruman started a Save XP Web petition, gathering since January more than 100,000 signatures and thousands of comments, mostly from die-hard XP users who want Microsoft to keep selling it until the next version of Windows is released, currently targeted for 2010.
