Yeah, it's sad about the (temporary?) RSX dilemma, but the good news is Linux is running on 6 of the 8 available cells, and even in FB mode the video is by no means dragging. I couldn't test the Beryl desktop yet, because I still can't get the network to function in wired or wireless mode, grr...
BTW, Yellow Dog has the latest Enlightenment E17 desktop with a lot of glitter and animation...and it ran very smooth.
There are 2 types of linux: Sabayon...and all the rest.
