Mediafour corp, released the shipping version of iPod software for the PC today called xPlay. (it’s long been in beta) Many journalists seem to think this is going to translate to huge sales for Apple, but I don’t think there are too many PC’s with firewire cards out there. They are using stats that show that PC’s are 95% Windows based and this is a huge market, but I bet the number of Macs out there that are firewire ready would far outweigh the number of people that are aware the iPod exists, willing to buy an Apple product, and have a PC with a Firewire card to actually use it.
