Two Wall Street Journal writers received reader responses that support the fact that the iPod “halo effect” is working. “In Monday’s column, we predicted that the combination of the iPod’s popularity and the increasing worry over viruses, security holes and spyware in Windows PCs will lead to the second coming of Apple as a home-computing power,” write Tim Hanrahan and Jason Fry. “To say that struck a chord would be putting it mildly. Boy, did we ever get mail–including a significant number of people who said that the iPod, Windows security concerns or a combination of the two had made them switch to a Mac or plan to do so.”
