Initial critics were up in arms over the allotted 6 months as the software giant usually provides a lengthier transition period. Michael Silver of Gartner saw the planned duration as having the potential to cause a ďreal messĒ for large businesses still relying on XP. He argues that companies would be forced to buy XP-ready systems prior to the deadline, or subsequently be stuck with Vista-only downgrades.
After April 2010, if a company were to buy new systems and wanted to stick with XP, it would have needed to purchase PCs with Vista Business or Ultimate for XP downgrade rights. The problem is, transitioning to Windows 7 from XP would then force them to also buy upgrade licenses - they'd essentially pay twice.
For now, naysayers are appeased with the extension Ė unless a service pack for Windows 7 actually shows up six months after the operating systemís appearance, of course.
