"I understand the reluctance to tangle with a new operating system, and upgrading Windows XP machines to Windows 7 may be more trouble than it's worth. But if you're buying new machines, I don't think it makes sense to downgrade them to XP. And if you have Windows Vista running in your company, the only reason not to upgrade is the cost of the new OS itself."
