As a whole, I whole-heartedly agree with your post. However, two comments to note:
"If you have a copy of IE, you have been screwed by monopoly power.
...But, you still buy IE, right?"
True that since MS Windows is a "monopoly" on PCs, having a copy of IE hiding on your hard drive means a monopoly shoved it down your throat. However, having IE in Windows is NO DIFFERENT than having Chrome in ChromeOS (they're both highly integrated, right?). My Android phone forces me to use Chrome! Oh noes! How about an iP*d or iPhone forcing me to use their Safari browser that came pre-bundled against my will?
Providing a browser by default is not, in my opinion, a problem. You have to get on the internet somehow to be able to download your real browser, right? They may not have distribution rights, or likely care, to stuff a competing product by default into their OS. Imagine the lawsuits that would occur if MS Security Essentials and Office 2010 web were free and bundled with every copy of Windows. Imagine the lawsuits. Last I checked, Apple distributed all sorts of iThingies in their OSX. Is anyone complaining? Have they been sued for providing Safari by default, like MS did with IE? No.
