I originally made this allusion about 3 years ago, before this all went to big courts.
There are a few car companies out there, and they all put stereos in their cars. Most of them allow standard attachment methods and case sizes so that the user or a professional can replace the stereo. Now a car is already a big piece of equipment with a lot of electronics and power equipment, it wouldn't be a big deal for a car company to put the volume knobs in the ceiling for "convenience" but it would break the compatibility with the large market of third party stereos.
Typically, the stereo is kept as a component to allow customer choice, and it is considered a benefit for a car to allow this future customization. Value added.
If Ford had 90%+ of the car market, they'd be reasonably expected to keep their stereo a modular component lest they be found guilty of antitrust leveraging one monopoly to gain another. Cars to stereos. The benefit is slight, the detriment is great. This is how I see thing, and this is how I see the integration of IE with Windows. Vision Shmision, there were ulterior motives far greater than the public benefit which was claimed and has yet to be proven. Besides that, the court already decreed (decried) that stuff like this was bad, and wrong, but failed te predict and legislate the future.
Now through predatory pricing / subsidization of IE, they have brought a barrier to market of undeniable consequence. Browsers can not make money in the traditional software manner, they must be tools to make profit through another business. The only reason AOL/Time/Warner/Netscape is legal is because microsoft exists, otherwise it too would be bundling and monopoly extension. We are building precedents for failure, and the incapacitation of capitalism.
Open up the API's, take funds to pay for 10 years of federal monitoring, and force the permenant retirement of Balmer and Gates from M$ or any of its primary affiliates. ... that and set somebody on fire.
