Could make the difference in battery time. or different battery capacity? I ran super_pi 20 to test basic CPU number crunching on my Core2Duo E6400 and EeePC900 (Sidux on both systems).:- EeePC - 71secs C2D - 18.5secs _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
