If you purchase an app from the app store, can it be loaded on two different ipod touch's? I think you can download directly to the ipod, but you can also download to a pc to load it on a device. I don't own a touch yet but am looking into buying two, and since they are locked down, I would like to know if I'd have to pay twice for each app. I am not planning on "jailbreaking" the device, but am comparing between the Ipod and Zune in loading extras. Thank you in advance for any input and advice.
