I don't know how the US anti-trust works, but I'm wondering why hasn't Microsoft ever been investigated about being a monopoly in desktop operating systems?
Thanks. I didn't know it. Microsoft is still a monopoly on desktop OS, even after this anti-trust investigation. To me, that's weird. Anti-trust didn't work?
Just having the most popular product doesn't mean you're liable in an anti-trust case, you have to abuse the position as well (IANAL though). There are no viable competitors for a PC desktop OS for them to abuse and haven't been since the 80-90's I guess.
A bit off topic, but to me it's interesting that they couldn't extend their desktop OS dominance to the mobile world when they launched Windows Phone with a huge war chest. That must have demonstrated how huge the disjunction is between desktop and mobile use-cases in general, or the strategy should have worked (and could have re-fuelled the anti-trust aspects)
