Apple can't really win on market share or their business model would be impossible to sustain on anti-trust grounds alone. The iPod was the only exception/fluke and IIRC there were some rumblings from the EU about it. The Bush DOJ was too 'business friendly' to worry much about it. Apple could make a market-share grab anytime they wanted to but they also realize it's suicide to do so. Better to own 30% of the market and 75% of the profits than 75% of the market and 30% of the profits. I don't know if they can sustain that but they probably won't shake things up until they are forced to. Don't mess with a good thing right?
