I think them doing this is a reall bad business move. You can get an xbox 360 for 1/3 the price of a ps3 and the games are just as good. Many nerds pay the extra money to get the linux option. It makes for a wonderful computer for your living room to check mail between games, play music, play dvds or divx videos.
As far as the comments about performance. If you tried doing something like rendering a full quality hour long home movie on your ps3,you may see why so
many people rave about linux on ps3. If the video app supports multiple
processor rendering, its absolutely lovely to use.
