Windows 7 Licensing 'Disaster' Looming for XP Users

From PC World -

Gartner analyst Michael Silver is predicting licensing problems with the well-reviewed Windows 7. Under Microsoft's planned enterprise licensing rules, businesses that buy PCs before April 23, 2010, with Windows 7 pre-installed can downgrade them to Windows XP, then later upgrade them to Windows 7 when they're ready to migrate. But PCs bought on or after April 23 can only be downgraded to Vista, which could cause major headaches and add more costs to the Windows 7 migration effort.
