Microsoft case study. I put the stock symbol for Microsoft [MSFT] in the title to highlight this is a bias study, in the fact that they [Microsoft] conducted the study or hired someone to conduct it and frame on their Why Microsoft site. Which is fine as long as you mention that to prospective customers. I’ve never held a sales position at the computer or business level so I’m simply letting you know it’s not like a Gartner Group research study or something like that.
Dell, Google, Yahoo, etc… even Acer probably all have their own case studies. Another would possibly be Amazon since they’re heavily into software as an infrastructure (IaaS) and software as a service (SaaS). Similar to Office 365 and Windows [and SQL] Azure.
