May be meaningful to the conversation ...

Reading through a Paul Thurrott article http://www.windowsitpro.com/article/windows-7/windows-7-enterprise-deployment-143885 he mentioned a company called Browsium who is stating that 80% of large organizations are running XP.

80% is high.  Really high.  So I went looking to see how valid this Browsium appeared to be.

http://www.browsium.com/

On their site they mentioned the statistics http://www.browsium.com/2012/07/30/windows7-are-we-half-way-there-yet/

That is where I found the qualifier "Though it's difficult to find hard data on the situation, we estimate...".  So the 20/80 needs to be weighted in your mind accordingly.

Without transparent numbers it is really hard to know.  I sure hope we are not in the early stages of a technology divide between consumer and business technology.  Charles love to use the phrase "general purpose".  In a divided world I guess we will need 2 phrases.
