Would you invest your hard-earned dollars in a company like this? Its revenues soared an average of 36% through the 1990s, but now it’s heading into miserly single-digit growth. It has long been a powerful engine fueled by major updates of its products, yet the next major one, an unprecedented five years in the making, isn’t expected until 2006. The company hasn’t made much headway in newer, promising markets. And its share price is stuck exactly where it was in mid-1998. Not buying, huh? Well, tough luck: You probably already own a piece of this rock, says Yahoo! Finanace.
