I installed Ubuntu on my PS3 waaaay back now it seems and even though the rest of the world went mad for Yellow Dog i though it was lacking in the user friendly stakes and installed another version of Linux, i will admit to being shit scared trying to dump that on my PS3 in case it all went FUBAR but i got there and it was a great O/S. After i upgraded my Hard Drive i neglected to re-install it and then i got too much content to bother reformatting the drive, so it stayed off. But this weekend i'll be ripping my power monster (1.4Ghz + 1Gb RAM) Ugly PC tower down to the roots and building it up with a spanky new O/S.
Don't forget that you can create more copies and pass the CD to as many people as you like.
