Listen to the video on the Apple - iPod shuffle - The first mp3 player that talks to you page. About 3/4 of the way in, in the "Using VoiceOver", they explain that when you sync your Shuffle with a Mac, it uses a male voice to talk back and a female voice when you sync to a PC. (Wish I knew them well enough to say which voice was which off-hand. Neither is Bubbles. ;^D)

Huh? Bizzare. Was listening wondering if I could chose another voice, and then BAM, well, guess I'll have to buy another PC.
