I'm guessing you're right about new sales vs. upgrades. However, I suspect there were a higher number of upgrades than say, Vista because the upgrade was priced pretty low. But I don't expect the number of upgrades to be higher than Win7.

Most corporations don't upgrade to a new OS, but rather wait for the regular lifecycle upgrade.


>Well said, Mel. I will take Craig at his word that there are some nice improvements in Win8. But the antipathy toward Metro is so widespread it has crippled adoption of the new version. I bet most of the Win8 "sales" are copies that come preloaded on new PCs, not upgrades. A switch such as you describe might change that.
