XP SP3 does not allow you to run IE6.
IE7 is installed as part of SP3 and cannot be removed 
without uninstalling SP3.

About 70% of web users run IE6 according to this.

I am happy with the advantages of IE7 fwiw. (Most notably 
tabbed browsing). I am not aware of why users do not wish to 
upgrade but no doubt there are some good reasons.

ALSO if you have installed IE8 Beta 1 you will not be 
offered SP3 automatically.
SP3 / IE* b1 are said to presently be incompatible.
