That was the foundation of my argument - since we both agree, why are you still arguing?
You know, I've seen you employ this tactic before. You're clearly losing an argument and you can't respond to the points brought up so you try to end the conversation. Sorry, but I won't fall for it. I'm arguing with the following statements:
Actually, the difference is that Apple could do what Microsoft was convicted of, and it would be perfectly legal. In fact, many of the things that Apple does would land Microsoft in hot water.
In fact, Apple could not do what Microsoft was convicted of without also being guilty of a crime. Microsoft was convicted of anti-competitive behavior. Anyone can engage in anti-competitive behavior even if they don't dominate a market (although admittedly, it helps). Apple, unlike Microsoft, has chosen to focus on competing rather than stifling competition.
Take the issue of Microsoft bundling IE to kill off Netscape and the subsequent conviction in 'United States v. Microsoft'. MS was not convicted of simply bundling a browser with their OS (in the same manner that Apple bundles software with OS X). They were convicted of acting in a monopolistic manner by taking deliberate steps to cripple the installation and operation of Netscape on Windows and to make it artificially difficult to uninstall IE. While their dominant market position did play a part in the ruling, they were found to have committed deliberate acts of monopolization, which is quite a bit different than just happening to have a really successful product and a dominant market share. As is the case in most legal issues, intent matters. Microsoft's intention was not just to compete with but to shut down the competition by any (illegal) means necessary. Apple, on the other hand, does not cripple competitor's software and does not prevent you from uninstalling bundled Apple applications. If they did those things, like Microsoft has, they would open themselves up to the same legal troubles.
As an example of Apple choosing not to engage in anti-competitive behavior when given the chance, look at the iPod. The iPod happens to be a very successful product that dominates its market. But Apple has not committed acts of monopolization to sustain that market share. They have not pressured distributors to stop carrying competitor's products, they aren't preventing competitors from accessing a user's music, pictures or video to sync to their own device (Apple won't allow other companies to profit by using iTunes built-in sync features, but anyone is free to write a sync implementation that directly accesses iTunes content) and they aren't preventing anyone from writing software to compete with iTunes. Notably, they also haven't attempted to tie your content to their own, proprietary formats as Microsoft has tried to do time and again.
I don't mean to dismiss the point on which we agree: yes, there are some areas where Microsoft is held to a different legal standard than Apple due in part to Microsoft's > 90% share of the PC market. But Microsoft's legal circumstances are also due in part to the fact that they've been convicted of abusing that position, multiple times. So, in much the same way that a convicted child molester is subjected to certain restrictions and suspicions to which the rest of us are not, many governments and corporations (parties likely to file suit) are understandably more wary of Microsoft than they might be of companies with less criminally tainted histories.
One further point is that Microsoft already does "many of the things Apple does". Things that, by your logic, should be illegal for Microsoft to do. One of the best examples is the XBox, which I'll bring up again since you ignored it the first time. The XBox is an entirely "closed" system in that the OS runs only on a restricted set of approved hardware. This is exactly the situation on the Mac and yet people like yourself love to point and say "Microsoft could never get away with that!". But they do, and it's fine because it's not anti-competitive. Let me repeat: making and selling a hardware-restricted computing platform is not in any way illegal for either Microsoft or Apple.
This has been fun so far. Do you have any other examples besides the "If Microsoft colluded with Intel it would somehow equal Apple not supporting the Atom" thing? Because that one was really, really weak.
