Now that there are so many devices and I’m using a laptop with a small hard drive (80GB), it is really hard to keep iTunes synced because you need to use half disk just to keep music, so you really want to have iPod or iPhone have its own libary and just add to it rather than have it synced. “ilounge”:http://www.ilounge.com/index.php/software/ recommends Anapod Explorer for Windows and CopyGear for Mac. Both cost money.
Here are some other Mac choices and a good list of iPhone related software at “iLounge.com”:http://www.ilounge.com/index.php/software/osx/
* “YamiPod”:http://yamipod.com. It is freeware equivalent for copying mp3s from your iPod/iPhone to your computer.
