Whoa, I've got to pay closer attention to this thread. Playing from USB? Awesome. I figure it has been stated somewhere (and this might be good to put on p1), but what will this include?
-iPhone with Lightning Adaptor?
-iPhone with Camera Connector Kit?
-Streaming audio from a computer (Spotify, webpage, etc)?
-Any properly formatted hard drive?
-A flash drive?
Ohhhh, very exciting possibilities.
