Another vote for Mandrake 9.1.
A friend of mine who has almost no experience with Linux installed it COMPLETELY on his own.
As a funny aside, I was supposed to call him so that I could talk him through the installation, but when I called, at 1 AM, we realized after a short while that he downloaded three CDs for the PPC architecture instead of i586. So, he and I spent about 4 hours on the phone, chatting, while he was downloading the correct three ISOs. When he was finally done and ready to install, my unlimited night weekends ran out so we had to end the long-distance call.
Later that morning, he logs on to AIM and informs me that he is now in Mandrake. It appropriately detected all his hardware.
