I don't think it would be fair on Microsoft to use these numbers here; 
they have been having uptake problems in general with their software 
recently and so I wouldn't really consider this representative of client 
upgrade trends in general. I don't see any reason to believe that uptake 
of a new version of IIS would be faster than a new version of IE in the 
current climate -- in fact IIS is more tied to OS releases than IE, so by 
your own arguments that makes IE more likely to rev faster than IIS.

Anyway, that's why I didn't look at the numbers for Microsoft's products 
released in the last couple of years. I should have mentioned that in my 
last e-mail.

I'll leave that decision up to the spec's editor; I just wanted to provide 
numbers to back up the earlier claim I made.

In my opinion the data says otherwise.
