The problem for EU was that Microsoft had a monopoly position in Windows and used this to bundle MSIE leaving out competitors as a choice during or right after installation. Same for WMP.

You could argue the same for Windows and FAT. There are 2 problems: 1) it takes very long till a court decides on such while meanwhile the complaining corporation has to survive... where is DRDOS, Corel, Novell, Sun, Netscape, Real now? 2) you can go on and on suing for such.

The 'FAT' patents are specific btw. They're about specific functions of FAT. It is not that you cannot use FAT without these functions; that is possible.

Personally, I believe we'll slowly but surely see more OS diversity as we move towards VM (Java, .NET, HVM) and the renting of capacity running on such ('cloud', Web 2.0) and 24/7 Internet connectivity. Meanwhile, Microsoft enters other markets. And in some of these markets they're not showing excellent customer support (XBox debacles). Its just that their competitor's offerings aren't so good either.

As for TomTom, to quote someone from another forum: "Get your new Tomtom Light! Fat-free, zero sugar!"
