Apple might have to face music of another kind in a class-action lawsuit that will likely be filed this month against the company in California. Disgruntled Apple users are gathering online support for the two separate actions, which seek to punish Apple for problems with its iBook laptop and its iPod portable music player. The lawsuits will address problems with Apple's default 1-year warranty period for the iPod and problems with Apple's iBook laptop display and video output. Apple has always had fanatical fans, and if these efforts are successful, they could be harmful to a company that relies on a steady stream of good news.
