Not to sound like a wacko but what is the difference between Apple and M$ business model??
Apple is about dominating on their own systems. Microsoft is about forcing other companies to bend to their will and dominate other companies systems.
Apple is not a monopoly for it cannot dominate the marketplace of system vendors so long as it only controls a system it makes. That is the key difference. Don't like Apples systems, buy from someone else. Don't like Microsofts system, well, meet the Windows tax and the bs that goes with it.
