I had to wipe off my powerbook to reinstall OS9 for my Protools and MBOX... I forgot what it was like to have a really snappy experience on my mac... Not to dis OSX, I love it. But its still too slow. OS9 screamed on my powerbook (ti 500 mhz) and OSX still chugs along. Its seems to get better from upgrade to upgrade, and I am sure it will continue to. But what an experience! Going back to the old and have it be so much faster. Sigh.
