I know of at least one very unhappy customer...a woman I work with just brought a new PC with Vista. Her printer doesn't work, and they told her she needs to buy a new one. It is a USB printer, only three years old. Granted, she could buy a new one for small money, but that isn't the point.
She was also angry because she got Office 2007, and her PC at work wouldn't open the files on things she worked on at home. I told her that was fixable, but she wasn't at all happy.
BTW...I have heard that Office 2007 is pretty well done. This woman just had bad timing to have the Office issue while she was still irritated with the printer.
