[citation][nom]eddieroolz[/nom]Linux violating Microsoft patents is a well-known fact.[/citation]
No, it's a well know claim. That was NEVER proven in court, in theory or otherwise. M$ has multiple targets for this claim (like RedHat, IBM, Canonical) yet they chose a dying company (SCO) to fight the battle in their place (and, as a result, they hit the final nail for SCO).
On another note, you can thank Linux for something really nice. All major Linux distributions and most minor have a "Method or apparatus for obtaining software and software updates directly from the operating system installed on the device, without the use of a browser. The method includes means of searching for software, reading reviews from other users and providing feedback on the software". I wonder... where would Android / Windows Mobile be if Apple was able to claim such a patent when it created the App Store?
That's why software patents are bad, evil and must be stopped.
