Except Windows was the dominant OS for almost 90% of the computer market and Apple, to the best of my knowledge, doesn't dominate the phone market yet. There are a bunch of Androids, CrackBerries and Palms out there, so closing the iPhone isn't anti-competitive yet,
I am not talking about the smart phone market. I am talking about the hand held device application market, specifically on the iPhone, iTouch and iPad, 2 of which aren't even phones, so the fact that there are Androids and other phones out there really doesn't matter when you discuss apps on an iTouch or iPad.
They are anti-trust not in the phone market but in the app market.
Keep in mind they just sold 300,000 iPads, that has to be an Internet tablet dominate market share, and it is subject to the same App limitations... so it really isn't about phones, Apple is stopping competition of Apps that run on products it SELLS to people.
There is a massive, world, multi-billion dollar market for apps on Apple handheld devices, and that is where they are acting in anti-trust manner.
No matter how bad they want to they don't own the market on apps for their devices, just like Microsoft doesn't own the market for what can be installed on Windows.
Blocking apps on Apple products should be met with the same reaction as if Windows blocked software from registering itself in Windows registry.
Imagine Ford selling you a car that only takes Ford approve gasoline, and they constantly updated your car to block your efforts to use gas from another vendor.
