A petition to “Save Windows XP” has drawn more than 111,000 supporters — and continued shots across the Microsoft XP vs. Vista bow, a battle that began with Vista’s release last year.

Among the concerns about Vista are the amount of computer memory and space it requires, its seemingly slower speed and frustration over the fact that third-party drivers for some printers and other devices are still not available from the companies that make those devices.

XP also will be available for sale until Jan. 31, 2009, by “system builders,” small businesses that custom-build “white box,” or generic, PCs.
