Any musician or recording engineer who has a stable and reliable DAW will only upgrade it under torture. The sheer number of tweaks and tests would take a week — you must be unfamiliar with the predictability of high-end audio hardware drivers... So I'll rather work with Arduino on a tiny MacBook screen and not go through that.
The mere idea that such a performance gap could exist between SL and Lion is difficult to grasp. Maybe there are other SL users out there who could provide some feedback? Everything working nicely on your end, or is everyone already on Lion?
I can't say we didn't try, no, on the the contrary, and I thank you very much for everything.
