Another integral part of an OS? (Score 2, Insightful)

I suppose Microsoft will claim that this is another integral part of an OS. While my first reaction is to scoff, I can imagine how that could be a good argument. I mean, Microsoft gaffs aside, any OS as popular as Windows will invite viruses, and not patching and protecting every Windows OS just opens all the others to attacks via trojans and bots. However, this is a really tough one for the lawyers to argue. If today Messenger is shipped with windows as a communication tool, then can a virtual VoIP client be shipped tomorrow as an updatd communication tool? How about a middle of a road version of SQLServer, with licenses that would fit the needs of small and mid-sized business just fine? Our anti-trust laws obviously need to be updated. I don't think for a moment that Apple is any better than Microsoft. In some ways, they may be worse. But, how can one stop them when our current anti-trust laws were made for steel an railroad barons? Are there any other countries that have better ideas of how to approach anti-trust in the digital age? Any examples of how it's been applied successfully?
