A recent Associated Content article is suggesting that XM and Microsoft are working together on some kind of satellite radio functionality for the Zune. Unfortunately their logic is a bit flawed.
The WiFi antenna also will help Microsoft to support XM radio on the Zune, something they've been looking into.
Both XM and Sirius have the ability to stream online. So if the Associated Content is suggesting that the Wi-Fi antenna will be used to stream satellite radio, then it doesn't really matter which big player is involved, because they will both be able to be used over Wi-Fi on the Zune.
But on the optimistic standpoint, are they suggesting that the Wi-Fi antenna will double as a satellite radio antenna? Is that even possible? Any smarty engineers want to shed some light on this?
