Just one more point. Please keep in mind that there are still lots of us that like Microsoft and IE and some of us don't even want to sue them.
There are always alternatives to using Windows. Then IE or any other part of windows doesn't enter into the picture at all. 
Just remember, this is my personal opinion. 
Who stated that I hate Microsoft or want to sue them, certainly not me? All I have stated is fact.
I use windows because, I like the interface, I have used windows since windows 3.1 and before that DOS, I can't recall any graphical user interfaces (perhaps GEM) of that era. I also used Unix for work so I am familiar with command based OS.
But the current linux options are not yet as easy to install as windows (for your average user), but they are getting there, it will become easier for first time PC buyers to chose a linux operating system.
It is a huge step for anyone to take (read captive audience) to move from windows to linux. They have to find an alternative to all their windows based programs and there has to be a degree of compatibility with the windows program that is being replaced otherwise all the work you have done is lost to you, unless you have a dual boot system.
Choice is always about compromise, and one of these about using windows xp is the embeded IE or turning your computer operations on their head to switch to linux hardly warrants thought. So alternatives have to be realistic, somewhat like not bothering to update IE because you don't use it, crazy.
