Next generation of iPods to have wifi?

Zephyr14z writes: "A TMCnet states that Apple has filed a patent for iPods that can purchase music wirelessly over the internet. This was an expected feature in the Zune, though it turns out not to be true. "While this could be an effort to fight the software giant and its product directly, it should be noted that Zune's built-in Wi-Fi will be limited to the file sharing between devices with no direct Internet purchases from the handheld," says Campbell."
