Playstation Portables -- not just for Windows any more.
Editor: 3 months of hard work, engineering and testing PocketMac For PSP means youll never need a Windows-based PC to sync your crucial data with your PSP and youll be able to do things with your PSP that PC users just cant. For examples, with every copy of PocketMac for PSP, there is a patent-pending technology that allows for your contacts to be transported to your PSP, a device with no built-in functionality for handling contacts. And this is a feature thats not available on the PC.

PocketMac For PSP takes care of everything for you. Install the software on your Mac in 3 minutes, hook up your PSP via USB or via the Memory Stick that comes with your PSP in a memory stick Reader. Configure which options you want enabled (Contacts, Music, Photo, etc.), Connect your PSP to your Mac and start the sync. Thats all thats required. Thats literally it.

Note: this software need you to buy before download. you can free download PocketMac for PSP 1.0 now.
