An unhappy iTunes Music Store customer is suing Apple, alleging the company broke antitrust laws by only allowing songs purchased from the store to only work with iPod, freezing out competitors. “The suit was filed on Monday in the U.S. District Court in San Jose,” reports Reuters. “One antitrust expert called it a long shot, but Californian Thomas Slattery is hoping for unspecified damages for being ‘forced’ to buy an iPod. The key to such a lawsuit would be convincing a court that a single product brand like iTunes is a market in itself separate from the rest of the online music market, according to Ernest Gellhorn, an antitrust law professor at George Mason University. There is legal precedent for such claims, but courts usually conclude competing products as viable alternatives, Gellhorn said.”
