In section 2.1.2. Which Architecture Is My Computer?, the PPC arch is listed in the table of architectures. PPC is now deprecated for Fedora as of Fedora 13.
Although this architecture doesn't necessarily need to be removed from the table, it needs to be clearer that readers won't find PPC in the official release trees. The *easy* way to do that would be removing the entry in the table.
