Some quick notes for clarification…
1. I refer to the USB cable as a “power cord to plug it into the computer.” It is, in fact, just a USB cable. There is NO power cord, just the USB cable.
2. My old wireless router was acting up and when I installed a newer and better one, YouTube videos loaded very quickly.
3. I say that I can get some music and videos from the iTunes music store. It’s actually music only. No direct video downloads (yet?).
