Buying a new Dell PC with Windows XP

I assisted a customer of mine 2 days ago with the online purchase of a new Dell PC that comes with Windows XP loaded and ready to go. We simply went to the Dell web site, clicked on Office (not Home), and then selected Small and Medium Business. We selected the machine we wanted and then customized the configuration. On the Ship To screen, we simply put the person's name, and when asked for the Company Name, repeated the customer's name. That's all there was to it. The new machine will be delivered within 3-5 business days. Oh, forgot to mention that it comes with a Vista installation disk so that should the customer ever want to migrate to Vista that can be done at no additional cost.
