YDL6 was just released a few weeks ago (from Terra Soft) and there are instructions on their web site for how to install on PS3. It runs pretty good but you don't have complete access to all system resouces but still a bunch of researchers are using linked PS3s as cheap supercomputers. However, all manner of free software is available for linux (games, office apps, etc..) so it depends on what you are looking to do. I personally bought my PS3 to use a media centre and linux picks up where the PS3 drops off in that I can play those media files, ogg, mkv, wmv, etc.. in high def that I could not otherwise (using the VLC media player). I also use it to compile digital photos into movies using mencoder. You will need a USB keyboard and mouse (I bought the Logitech EX110 which works great for both PS3 and linux, uses only 1 USB port and is wireless). I have the 40 GB PS3 and formatted the drive to give 30 GB to linux and 10 to PS3 which is plenty for both (but I have also attached a 500 GB external USB drive for the media files). YDL6 can be bought from the Terra Soft store for $50 now or you can wait until March 3rd when it will be avail as a free download from their web site. Cheers.
