To make a fair assessment of upgrade adoption rate, you have to discount 
IE7 installs due to bundling with new computers, and you have to compare 
the rate of adoption against other browsers. For example, Safari 2 to 
Safari 3, or Firefox 1.5 to 2.0. Unfortunately, as you say, it is hard to 
get reliable public statistics.

However, that the second most widely used browser today is one that 
shipped over half a decade ago, despite it being obsolete in its own 
product line _and_ having been marked for auto-upgrade to the latest 
version by its manufacturer, is a pretty clear indication of what I am 
talking about.
