This is a breaking story. From Bloomberg:

The U.S. Supreme Court ruled that consumers can press ahead with a lawsuit that accuses Apple Inc. of using its market dominance to artificially inflate prices at its App Store.

The 5-4 ruling May 13 could add to pressure the company faces to cut the 30 percent commission it charges on app sales. Lawyers pressing the case have said they will seek hundreds of millions of dollars on behalf of overpaying consumers.
