How does Rockbox compare to iPodLinux?
iPodLinux is a project to port Linux (actually uClinux, a derivative of the standard Linux kernel) and associated userspace utilities to the iPod. Rockbox is a project to create cross-platform music player firmware from scratch, with the goal of being the best music player possible. Rockbox is not based on Linux or any other operating system, it is written completely from scratch. While iPodLinux also includes music player functionality (and Rockbox contains plugin platform functionality), the goals of the two projects are different.
