So here I am contemplaiting the purchase of an iPod Shuffle. My current 10GB 1st gen iPod is showing its age and having a few difficulties. Non of the current iPods are drasticly different (I still want a super cool function like wireless before I buy a new one). But the Shuffle seems like it might fill a void until A) my current iPod fails or B) a wireless iPod comes out (hooks to the airport express!!!!) Until then the Shuffle would work well and the shuffle playlist sounds cool. But, will it work with USB 1 that I have on my Rev A 12" PB?!!?! Yes, I know USB 2 is backwords compatible so it should technically work, but will it take forever and a day to load 1GB of music over USB 1?
