1. It's Not XPThe vast majority of organizations decided to skip Windows Vista. It was a smart move. Microsoft's last operating system was rife with problems. Several hardware and software products didn't work with the operating system when it was released. It was subject to security issues. And perhaps worst of all, it failed to deliver a reasonable improvement over XP. But now that Windows 7 is everything that Vista should have been, companies using XP first need to realize that it's nothing like their favored operating system. There will be growing pains when switching between interfaces.
