I am purchasing a new powerbook 12" but would like to skip out on the superdrive because I already have a perfectly fine SONY DRU-510a in my PC. I want to buy a $40 firewire enclosure and plug it into the mac on the few occasions where I might actually need it. Anyway one know where I can find out if this is possible, how I do it, or if it flat out cannot happen? Thanks alot!!!
