I just got my iPod shuffle and after plugging it in to my new Powerbook with USB 2.0, and selected autofill, it proceeded to download the music...but at a very slow speed. I have had a regular HD based iPod before and remember it transfering songs very quickly. So my question is to those out there with 1GB iPod shuffles...how long does it usually take it to fill up the entire 1GB. Is there something I'm doing wrong? Thanks for any help!
