Beware of the installer.
A typical linux install will ask which partition to install on, and even allow resizing and such using programs like gparted. This is because the typical linux user multi boots to windows and other linux distro's.
On a media computer, it is smart to have a linux partition and a data partition, so that the OS can be reinstalled without deleting the data.
This is the only 'major' linux distribution I've ever seen that does not even bother to warn the user before wiping hard drives.
I've installed lots of linux distro's, this is the worst.
After telling the installer which drive to install on, I fully expected it to ask which partition. It didn't. Lame.
