yes, you are right about being on the mac platform.
let me fill in a bit of info...i've had cubase for years but i HATED it when i switched to mac (slow!). then os x came out and i needed to upgrade and decided not to. so i'm in a position where i can upgrade my license for about $150, get logic at the educational discount for $199 or pro tool at edu discount for $150.
also, i've got an m-audio fw410 from several years back, which isn't a terribly good interface but is serviceable.
