MS and Windows is simply not related to the Apple situation, unless MS decided to only allow Windows on its own hardware thus creating a closed ecosystem.
The closest analogy to Apple is the game console industry. Even then it's a different scale.
IMO, the App Store situation is an entirely new class of problem unlikely to be solved in this case. It doesn't easily fall under existing monopoly regulation, and does have some advantages for consumers along with disadvantages. Unfortunately, I think Apple is being short sighted here. By not addressing the most egregious issues (30% for example), they are setting themselves up to be regulated which will probably end up being worse for everyone. A sledgehammer will end being used where a scalpel was needed.
