|In case you're wondering why Arch Linux is better...|
Pacman and ABS. This is Arch's package manager and PORTS-like build system. They work perfect. What more can I say? Pacman will fetch binary packages from servers (there's 3, Current, Unofficial, and Unstable) and install and upgrade your system.
It is able to fully upgrade your system without a hitch. For example, the Arch CD comes with GCC3.2.2. I upgraded to GCC3.3 (and then to 3.3.1 later) without any problems.
I was able to upgrade kernels perfectly as well. The system really works.
