Well, if you ask me the reviewers at "Sound on Sound" aren't exactly
known for their competence... and I would like to think that after all
those years they should be able to do better than that and provide
some hard facts when they review products, but apparently not...
"overload indicator started flashing"... how ridiculous is that.
Anyway, like you said it is interesting and agrees with my observation
that most products aren't really optimized to run on multiple kernels.
But then again isn't this what Snow Leopard is supposed to take care
of automatically in the future...?
