Some analysts are saying iTunes for Windows may be joining the Windows side of the digital music industry too late, as there are already similar services for Windows users, such as MusicMatch,, and Napster 2.0, reports Reuters. “They’re going to have a serious problem with the Windows community,” said Rob Enderle, principal of market research firm the Enderle Group. “If they could have gone there first, they could have carved out a beachhead.” Analysts are also noting that the iTunes Music Store could strike a familiar tune for Apple: “Apple was the first to popularize the graphical user interface, but was ultimately leapfrogged by Microsoft.”
