> They have a real competitor, yet it’s not a competitive market.

Yes, that's completely consistent with the Brandeis view of antitrust. Cartels are not a competitive market.

> Everyone was crying antitrust and it never went anywhere.

Not facts. It resulted in a successful prosecution by the Clinton DOJ, and Microsoft was ordered to breakup in 2000. The company appealed (dragging past the election) and it was settled by the Bush DOJ, which obviously resulted in weaker policies since the Bush lawyers subscribed to the Borkist view of antitrust.

> If you think anything worse is going to happen to Apple with their 20% market share, or even if you somehow inflate the number to 65%, think again. It’s not going to happen under antitrust law. If anything is going to happen it’s going to be new laws.

Guess we will see. Seems to already be happening based on the defensive moves these companies are making in response to more aggressive regulators, but I agree new laws would help move things along. I didn't "somehow" inflate it. I looked at the recurring revenue streams from the app store instead of device sales, because app store revenue is a massive stream of profit, and devices are low-margin commodities.
