Critics of Apple have long complained about the company’s insistence on proprietary software for all of its products. A class action suit underway now argues that by only allowing music purchased at Apple’s iTunes store to play on iPods, Apple has created a monopoly.

The case is now in court, and a judge has ordered Apple CEO Steve Jobs to testify.

Jobs has been on medical leave since January, though he did make a brief public appearance for the release of the iPad2.
