Fedora Core 4
If you've heard of Linux, chances are you've also heard of Red Hat. Fedora is Red Hat's open source project. Like Ubuntu, Fedora has a frequent release cycle and includes the most bleeding-edge software releases like Linux kernel 2.6.11 and GNOME 2.10.0. Fedora only includes free, open source software in its distribution; there's no Real Player or other proprietary products included. If you're a purist, Fedora Core is a good choice.

Not surprisingly, Fedora Core uses RPMs to package software. Software updates are taken care of by Up2date and YUM. Up2date is Red Hat's own product, while YUM stands for "Yellow dog Updater, Modified," an RPM manager with functionality similar to Debian's APT. Yellow Dog is yet another Linux distribution, but specializes in PowerPC (Mac) support. Fedora includes over 1,800 RPMs on the DVD with more available online. The OS isn't supported by Red Hat, but there's plenty of community support and a large user base so finding answers to your questions should be simple.
