I've got a Windows formatted iPod mini just now, and I've also got a mac now, are there any advantages of re formatting my iPod to mac? I've noticed that sometimes when I switch songs on my iPod, occasionaly (well, at least once or twice a day) it freezes for about 5 seconds and then switces to the next song, but when I press the back button, the previous song plays just fine. Do you think re formatting could help with this?
