Japanese blog Macotakara claims to have information on the next iPod Nano saying for the first time ever the device will be Wi-Fi equipped allowing you to use iTunes in the cloud and download music from the iTunes Store.
Next iPod nano may equip Wi-Fi antenna on side of that case, and support iTunes Music Cloud in order Apple to provide a iconic product to promote the largest Music Store in the world.
Having the iPod Nano have Wi-Fi connectivity might attract users who want a low cost music player for say a workout while allowing them to have Wi-Fi to download or stream music connected to a hotspot.
