I don't like BOINC, it's no where as fun as the old SETI client... Then again it had a ton of plugins, including ones to process where the units where found to have positive data...
The PS3 seems to be working pretty good... I had to disable processing on my laptop after an issue with peer guardian i was having 20gb files generated with dummy backup data... which is bad considering all i have is a 50gb hd lol...
