US Justice Dept opens IBM antitrust probe

I always find it ironic that companies choose actions determined to against the public interest instead of solid business practices.

Out competing your smaller opponents is far different than undercutting them. Apple is essentially safe from an antitrust in commercial computers, because essentially every tom, dick and harry can open up a computer store and charge less than Apple for an adequate computer. However people choose to purchase Apple products not because there's no alternative (ironically Apple is commonly seen as the alternative in computing) but because it's regarded as a better choice.

IBM and other computer manufacturers wouldn't get themselves into trouble if they would just make computers and mainframes that people wanted. However, they go the grey route and make sure they're the computer people can afford by undercutting prices and selling in bulk while they have a monopoly of the market.
